An excellent free program for finding duplicate files (pictures, photos, music, etc.).

Let's imagine this situation... Six months ago you purchased a brand new terabyte hard drive. And so, when you try to download another movie from torrents, your PC tells you that this is how it is, but there is no more space on your hard drive :). Nightmare!!! Guard!!! How can this be, it was a whole terabyte:(((?!!

And the whole problem may lie in the fact that too many duplicate files or even entire folders have accumulated on the new hard drive.

If you start manually rummaging through your “treasures” downloaded from the Internet, you can spend more than one day finally finding two identical installers of the same program or several copies of the same song!

But you can do much wiser - instruct your PC to carry out “soul-searching” and, based on the results of this process, decide what needs to be thrown away and what to leave.

However, in basic Windows versions There is no function for searching for copies of files, so we will have to use third-party software for this matter. One of the best free solutions to this type of problem is the program DupKiller.

It can do almost everything you need for a comfortable and quick search for duplicate files, so it can easily compete with paid applications eg Duplicate File Remover:

Comparison of the DupKiller program with its paid analogue Duplicate File Remover

The only major drawback of DupKiller is the lack of support for NTFS Hard Links. That is, the program cannot create links to the selected file for it to work with several separate applications (without harm to the latter) :(.

If you are not going to rummage through folders with setup files of various programs installed on your PC, then DupKiller is just the tool that will allow you to put things in order on your hard drive.

Installing DupKiller

To install the program, we need, as always, to open the downloaded archive and run the installation file. In the first window that appears, we will be asked to select the installation language (we choose, of course, “Russian”), and then it all comes down to simply accepting the license agreements and confirming all offers :). Once the installation is complete, we will see the DupKiller working window:

DupKiller Interface

The program interface is quite simple and convenient. At the top we see a standard menu bar, which we will hardly use, on the left is a section bar, and on the right is a direct workspace with the necessary buttons and options.

A rather big advantage of DupKiller is the step-by-step automatic switching of tabs on the left panel after you perform one action or another. Thus, something like a step-by-step wizard for working with the program is implemented, which is undoubtedly very convenient for a user who is not familiar with the new interface.

By default, after launching DupKiller, we are taken to the “Disks” tab. Here we can use checkboxes to indicate those sections that should be scanned for duplicates.

For the first time, I advise you to perform a full scan in order to find out the real picture of what is going on on your entire hard drive, so don’t linger on this tab and click the “Scan” button.

After the scanning process is initialized hard drive we automatically go to the “Statistics” tab:

Here the entire process of scanning the hard drive is displayed in a visual form. In addition to the log file window in which DupKiller operation statistics are recorded, we can obtain some information from the status line at the very bottom of the program’s working window.

First of all, this is the number of files found. While in the statistics section, we can pause or completely cancel the scanning process, but in the latter case we will have to start new search from the very beginning.

The scanning will not take too long (it all depends on the size of your hard drive). For example, I had 80 Gigabytes scanned in a little less than three minutes :). At the end of the process of searching for duplicates, we will be immediately redirected to the last section “List”:

Removing duplicates and other unnecessary files

In fact, this is the most important window of the program, so let’s look at it in detail. The first thing I advise you to do is expand DupKiller either to the full screen, or stretch its window horizontally so that it is convenient to see the entire status line at the bottom.

On it we will see the number of duplicate files, their total size, and when selecting duplicates to be ruthlessly destroyed, also the total size that will be freed up after their removal.

The next step is to sort all the duplicates found by the amount of space they occupy on the hard drive. To do this, you just need to left-click on the “Size” inscription (fourth column of the list).

After this, all files will be sorted in ascending order of their “appetites” for hard disk space. That is, the “heaviest” files will be at the end of the table, and the smallest ones will be at the top (you can do the opposite by clicking on “Size” again and waiting for a new list to be compiled).

Now you can start selecting necessary files. In the main list they are divided into groups that display duplicates of the same file in different folders (with their indication, of course).

For some types of files (text and graphic, and when the plugin is activated, also audio) DupKiller has a preview function. That is, as soon as you select a specific file, a window immediately pops up in which you can see its contents without opening it.

For small files, using this function seems quite convenient, but large files take quite a long time to open, which greatly slows down both the operation of the program and the system in general.

Therefore, I advise you to deactivate this function by clicking the “Disable Preview” button (you can re-enable it by clicking the “Preview” button on the toolbar above the file list).

When all the preparations are completed, all we have to do is tick the unnecessary duplicate files and click the “Delete selected files” button on the toolbar. That's it - we got rid of excess ballast on the hard drive and freed up much-needed space for re-cluttering :).

As you can see, everything turned out to be quite simple - you will do it right the first time without any additional installations were able to “conquer” an impressive amount of space on the hard drive.

However, DupKiller is not without fine settings, but on the contrary, it is simply replete with them. As you understand them, more and more new functions of the program will open up for you! Let's look at the most important of them.

Additional features

So, DupKiller allows you to scan not only the entire hard drive at once, but also individual folders:

Files and folders

To configure the directories to be checked for duplicate files, you need to go to the “Files and Folders” tab. There are two sections here.

In the top (“Searched files”) you can specify which types of files need to be compared (all are activated by default). And in the lower one (“Searched folders”), switching to the “Only specified folders” mode, set a list of folders that should be checked for duplicates.

Folders can be added either using the “Add” button or by simply dragging and dropping, which can sometimes be an even more convenient option.

Exceptions

The next tab - “Exceptions” - allows us, on the contrary, to specify those file extensions and folders that should not be included in the scanning process:

Settings

Working with this tab is similar to the previous one, so we will not focus our attention on it, but move on to the next section - “Settings”:

This is where you can have fun! :) Here we can set the criteria by which files should be compared, the degree of similarity at which the files will be considered the same, the sizes of the processed files, as well as many other parameters.

If these settings are not enough for you, then DupKiller also has “Other settings” :)

If in the previous section there were parameters related directly to the process of scanning files and folders, then these settings relate more to the program interface.

Here you can set the priority of the search process, change some parameters for displaying the list of duplicate files, and also work on saving and restoring settings. Regarding the latter, there is a little secret ;).

DupKiller can be made to work in portable mode (from a flash drive or disk). To do this, you need to activate the “Save settings” item in the “File” menu and save the file with program parameters in the folder where DupKiller is installed (by default C:\Program Files\DupKiller). Now all that remains is to copy the above folder to removable media and you're done ;).

The last group of program settings concerns the “Delete” parameters of files:

Here all the settings are extremely clear, so we do not focus on them, but consider the global Advantages and Disadvantages of DupKiller.

Advantages and disadvantages of DupKiller

byte-by-byte file comparison;
file preview function;
flexible scanning settings;
auto file selection function;
ability to use as a portable application.

There is no way to create hard links to files.

Conclusions

As you can see, DupKiller has virtually no disadvantages, so it can be recommended as an ideal free program for war with clones of files on your hard drive! Good luck to you and may the FORCE be with you!!! :)

Good day...Today in thisIn this article we’ll talk about such a good program as Auslogics Duplicate File Finder - This is an absolutely free program for finding and removing duplicate files from your computer. Using this Auslogics Duplicate File Finder program, you can find duplicate files located on your computer, and also remove them from your computer.

What is a duplicate file

This is a copy of a file located on the computer in a completely different directory, or disk, folder and has the same name as the original file, weight, and extension. There are duplicate files on almost everyone personal computer, even if you did not make a copy (duplicate) of your files (for the purpose of any system failures), they will still be on your computer.

Where do duplicate files come from?

For example, you downloaded two albums of songs by the same artist from the Internet, mostly the compositions of the songs in the collections are repeated, i.e. the same, and the same with photographs - there are identical photos in different folders, over time, these duplicate files become more and more numerous on the computer, and accordingly they take up a lot of space on the hard drives of your computer or flash drive, and this also leads to the slowdown of your PC system.

Therefore, they must be removed periodically. By removing duplicate files you can significantly increase free space on your PC's hard drives - . You can download this program via this link. The program is in Russian and has an intuitive interface, so understanding the program will not be that difficult.

Find and remove duplicate files using the program - Auslogics Duplicate File Finder

Unpack the archive, click on installation file program, in the program window that opens, click “NEXT”

In the next window, we agree to the license “I accept the agreement” and click “NEXT”

Then check the box "Create a desktor icon " create a shortcut on the desktop, click “Next”

Setting up Auslogics Duplicate File Finder

We launch the program and in the window that opens on the left, select the one we need hard drive or external media, I recommend selecting all disks to scan for duplicates.In the center of the window, select the types of files that the program will search on the PC. There are two search options. “Among all file types” and “Among only these file types” „.

I recommend selecting the second “Among only these file types” in order to avoid deleting necessary files that are used by the system. You can also uncheck a section if you do not want to scan it for duplicate files. After selecting the desired settings, click “Next”.

The next window will have the settings “ignore files smaller than 1 MB.” You can also select the setting for “ignore files larger than 1 GB.” You can also change the created values in the program to your own. I'll check both boxes. Click “Next”.

In the next step, you can select settings for searching for duplicates, ignoring the file name and creation date. By default, the program checks the “ignore file creation date” checkbox.You can select both items, then the program will do a wider scan of the selected hard drives. Choose required settings and click “Next”.

In the next window, choose what to do with the found duplicates. The program defaults to deleting to the trash so that you can restore those files that you think were deleted by mistake.In the second point, file recovery will occur from the already created archive. In the third point, everything is clear; files from the computer are deleted permanently. Select the desired settings and click “Search”.

Finding duplicate files

The program will begin searching for duplicate files. Scanning hard drives takes place in 3 stages

The program determines the number of folders
After this, the program finds those folders that contain the types of files that you selected in the search settings, then the date and name of the file creation are checked
After which a full check of hard drives and external media is performed

Upon completion of the search, a window will open with the result of scanning the program for duplicates. On my computer, the program found 71 duplicate files, size 635.88. The program window displays the file name, its location on the disk, the file size, and the date it was last modified.

Next, click on the “Select” button " at the bottom of the window and select the most appropriate item to remove duplicate files. I selected “Select all duplicates in each group” then click “Delete selected files” " and confirm in the window that opens with the OK button.

You can also mark files manually by checking the box next to the selected files, and then click on the corresponding delete button. All duplicate files that you marked will be deleted in the directory in which you previously specified to delete them (in our case, this is the trash).

Then close this program. Auslogics Duplicate File Finder designed to find duplicate files on hard drives and external media. This is where I will end this post, I hope it turned out useful.

Sometimes in everyday computer activities the task arises of finding duplicate files. There can be many reasons for this: lack of space on your hard drive, attempts to reduce entropy in your files, dealing with photos from your camera that were dropped at different times, and many other necessary cases.

You can find a large number of programs on the Internet that allow you to search for duplicate files. But why look for any programs if a smart tool for such work is usually always at hand. And this tool is called Total Commander (TC).

In this article I will show all the methods based on Total Commander versions 8.5 , in this version, the search for duplicate files has become very rich in functionality.

!!!A small important digression. What do you mean by duplicate file? Two files are IDENTICAL only if they are exactly the same bit by bit. Those. Any information in a computer is represented by a sequence of zeros and ones. So, files match only when they completely match the sequence of zeros and ones that make up these files. All talk about how you can compare two files on any other basis is deeply erroneous.

TC has two, essentially different, methods for finding duplicate files:

Synchronize directories;
Search for duplicates;

Their features and application are best illustrated with examples.

1.Directory synchronization.

This method is used when your two folders being compared have an identical structure. This usually happens in many cases, here are a few of them:

Have you regularly archived your work folder? After some time, you need to find out which files have been added or changed since the archive was created. You unpack the entire archive into separate folder. The folder structure in it practically coincides with the working one. You compare two folders “original” and “restored from archive” and easily get a list of all changed, added or deleted files. A couple of simple manipulations - and you remove from the recovered folder all the duplicate files that are in the working one.
You are working in a folder on network drive and regularly make a copy to yourself local disk. In time your working folder has become quite large and the time spent on full copy, has become very large. In order not to copy the entire folder each time, you can first compare it with the backup one and copy only those files that have been changed or added, and also delete files in the backup folder that were deleted from the main one.

Once you get the hang of it and feel the full power of this method, you yourself will be able to come up with thousands of situations where the directory synchronization method will be of great help to you in your work.

So, how does everything happen in practice? Let's get started.

Let's assume we have a main folder "Working", which contains the files with which you are working. And there is a folder "Archive", which contains an old copy of the folder "Working". Our task is to find duplicate files in both folders and remove them from the folder "Archive".

Open TC. In the right and left panels, open the folders being compared:

Press menu “Commands” - “Synchronize directories...”

The directory comparison window opens

Next we need to set the comparison parameters. Put a tick in the parameters “with subdirectories”, “by content”, “ignore date”

"with subdirectories"— files in all subdirectories of the specified folders will be compared;
"by content"- this is the key option that forces TC to compare files BIT by BIT!!! Otherwise, files will be compared by name, size, date;
"ignore date"- this option forces TC to show differing files without trying automatic detection directions for future copying;

!!! Only files with the same names will be compared!!! If the files are identical, but they have a different name, then they will not be compared!

Press the button "Compare". Depending on the size of the files, the comparison can take a very long time, do not be alarmed. Eventually the comparison will end and the result will be displayed in the bottom status line (section 1 in the figure):

If the buttons in the “Show” section (section 2 in the figure) are pressed, then you will see the comparison result for each file.

— this button enables the display of files that are in the left panel, but not in the right;

— this button enables the display of identical files;

— this button enables the display of differing files;

— this button enables the display of files that are in the right panel, but not in the left;

If you initially have all display buttons turned off, then the result of the comparison can only be assessed by the status bar (section 1 in the figure above), in this case we see that 11 files were compared, of which 8 files are the same, 2 files are different, and There is also a file in the left panel that is not in the right panel.

To complete our task, it is necessary to leave the display of only identical (identical) files, so we turn off all other display buttons

Now we only have identical files left, and we can safely delete them in the folder "Archive". To do this, select all files. The easiest way to do this is by pressing the universal combination CTRL+A. Or first select the first line with the mouse, then press the key on the keyboard SHIFT and without releasing it, select the last line with the mouse. As a result, you should get something like this:

The final step is to right-click on any line and select the item in the menu that opens "Delete on the left"

TC kindly asks us about our desire,

and if we press "YES" then it deletes all marked files in the folder "Archive".

After this, the two folders are automatically compared again. If you do not need a repeated comparison, the process can be interrupted by clicking on the button "Abort" or press a key ESC on the keyboard. If the repeated comparison was not interrupted, and we turned on all the display buttons, then we will see a window like this

All. The task has been completed. All identical files were found and deleted in the folder "Archive".

2.Search for duplicates.

Fundamental difference this method from the directory synchronization method is that TC ignores the names of the files being compared. In fact, it compares each file with each, and shows us identical files no matter what they are called ! This search is very convenient when you do not know either the folder structure or the names of the files being compared. In any case, after searching for duplicates, you will receive an exact list of identical files.

I will demonstrate finding duplicates using one practical task, finding duplicates of personal photos. Quite often you dump photos from your digital gadgets. Often the situation gets confused, something is reset many times, something is skipped. How to quickly delete files that have been dropped multiple times? Very simple!

Let's get started.

Let's say you always dump all your photos into a folder "PHOTO" on drive D. After all the resets, the folder looks something like this:

As you can see, some files are located in folders named by the date of shooting, some are dropped to the root of the folder "_New" And "_New1"

To start searching for duplicates, open the folder in which we will search in any TC panel. In our case this is the folder "PHOTO"

Next, press the key combination on the keyboard ALT+F7 or select from the menu “Commands” - “Search files”

The standard TC search window opens. String "Search files:" leave it empty, then all files will be compared.

Then go to the bookmark "Additionally" and check the boxes “Search for duplicates:”, “by size”, “by content” and press "Start Search".

The search can take a VERY long time, do not be afraid of this, since there are a huge number of comparisons of a large volume of files. At the same time, the progress percentage is shown in the status bar

When the search ends, a search results window will open, in which we press the button "Files to panel"

In the search window and in the panel window, identical files are collected in sections separated by dotted lines

Each section displays the file name and full path to the file. The names of IDENTICAL files can be completely different!
In this case, it is clear that the same photograph was recorded THREE times, twice under the same name( IMG_4187.JPG) and the third time this photograph was recorded under a completely different name ( IMG_4187_13.JPG).

Next, it remains to select unnecessary identical files and delete them. This can be done manually by selecting each file by pressing a key Ins. But it takes a long time and is not effective. There are better and faster ways.

So our task is to remove duplicate files in folders "_New" And "_New1".
To do this, press on the additional keyboard, the large key on the right [+] . Typically, using this key in TC, files are selected by mask. The same operation can be done through the menu “Selection” - “Select group”

This opens a window "Selecting duplicates", in which we go to the tab "According to catalogs"

Initially on the tab "According to catalogs" all directories found during the search are highlighted

Put a tick “Also select subdirectories (if selected manually or using a template)” and press the button "Remove from everyone". In this case, the selection in the list is removed from all directories

Now all that remains is to manually select, by clicking the mouse, in the list those directories in which duplicate files need to be deleted. This will highlight all subdirectories in the selected directory.

That's it, press the button. "OK" and again we find ourselves in the panel with the found files. Only now all the necessary duplicate files are already marked in red. Notice the section of three identical files. It highlights two of the three, as needed.

That's it, all that remains is to delete the selected files using standard methods TC. Can be pressed on the keyboard F8, you can press DEL, you can press the button "F8 Delete" on the screen. TC will ask you again about your desire to delete files,

press "Yes" and that's it, the files are deleted! Only non-deleted unique files remain in the panel.

The method described above is not full instructions for searching and removing duplicates. In the window "Selecting duplicates" There are significantly more options for selecting files. Full description would take up a very large space.

Let these examples serve as a starting point for you to start effectively manipulating your files.

A program for finding duplicate files is most often needed by users who store a large amount of music, photos and documents on disk.

And, although you can delete such unnecessary copies manually, specialized applications can save a lot of time.

Especially if the files are located in different folders or in .

You can search for such duplicates using the universal software or designed for a specific data type.

In the first case, the search speed increases, in the second, the probability of finding all copies increases.

Content:

Universal Applications

Universal applications for finding copies mainly work on the principle of comparing file sizes.

And, since the probability of the same number of bytes in different photos is practically zero, identical values are considered a sign of a duplicate.

Sometimes the algorithm provides for checking names - also an important parameter for the search, especially since the same data in most cases also matches by name.

The advantages of the programs are the ability to find files of any type with their help and the relatively high speed of operation. Disadvantage: lower detection accuracy.

So, for example, none of these utilities will consider the same file saved with different resolutions to be a duplicate.

1. DupKiller

And among its advantages we can note:

ease of setup;
setting multiple search criteria;
the ability to ignore some files (with a certain size or creation date, as well as system or hidden ones).

Important: If files with a size of zero are detected, they do not have to be deleted. Sometimes this may be information created on another operating system (for example, Linux).

Rice. 4. CCleaner system optimization program can also search for duplicate files.

5.AllDup

Among the advantages of another program, AllDup, we can note support for any modern operating system Windows systems– from XP to 10th.

At the same time, the search is also carried out inside hidden folders, and even in the archives.

Although the comparison of information by default occurs by file names, so it is advisable to change the settings immediately.

But during the search process, each duplicate found can be viewed without closing the application.

And if a copy is found, you can not only delete it, but also rename it or move it to another location.

Additional benefits of the application include completely free work for any period of time.

In addition, the manufacturer also produces portable version in order to search for copies on those computers on which installation of third-party software is prohibited (for example, on a work PC).

Rice. 5. Search for files using the portable version of AllDup.

6. DupeGuru

One more useful application The one that searches for duplicates with any extension is DupeGuru.

Its only drawback is the lack of new versions for Windows (although updates for MacOS appear regularly).

However, even a relatively outdated utility copes well with its tasks when working in newer operating systems.

With its help, even system files are easily detected, and the menu is intuitive and in Russian.

Rice. 6. Detecting copies using the DupeGuru utility.

It is noteworthy that, in addition to the usual universal option, the manufacturing company has created a utility for searching for files of a certain type.

There is a separate version for images and another for music.

And, if necessary, clean your computer not only of documents and system files(which, by the way, need to be deleted very carefully - sometimes it’s even worth leaving an “extra” copy rather than disrupting the system’s performance), it’s worth downloading these applications as well.

7. Duplicate Cleaner Free

Duplicate Cleaner Free, a utility for detecting copies of any file, has the following features:

filtering data by extension;
Russian interface language;
possibility of free use;
high speed.

Its disadvantages include minor limitations when searching for images (for this it is recommended to purchase a paid version) and not entirely accurate translation of individual menu elements.

However, due to its effectiveness and ease of use, the application enjoys some popularity.

Finding duplicate audio files

If the search results for duplicates are not satisfactory for the user, you can consider an option designed for specific files. For example, for accumulated on disk.

This need often arises when downloading several albums and collections of the same artist at once - often the same tracks end up in different folders.

They can have similar sizes and differ, by and large, only in names. Especially for this, there are utilities for searching for similar melodies.

8.Music Duplicate Remover

Among the features of the Music Duplicate Remover program are relatively quick search and good efficiency.

In fact, this application “listens” to the composition and compares it with other audio files.

At the same time, naturally, its operating time is longer than that of universal utilities.

However, the amount of data checked by the program is usually tens of times less, so the average scan duration rarely exceeds a couple of hours.

Finding copies of photos and other images

Just as often, the user may need to remove duplicate images.

Especially if your hard drive contains several collections of personal photographs, sorted by date or location of shooting.

With the help of special software, unnecessary photos and pictures will be detected and destroyed, and there will be more space on (and other storage).

11. DupeGuru Picture Edition

The application for searching for identical pictures is another version of the DupeGuru utility, which can also (and is even desirable) to be downloaded even if there is a universal version.

At the same time, photo analysis also takes longer compared to searching for files of any extension, but the result is worth it.

Images are detected even when there are several duplicates of the same image on the disk, but with different resolutions and, accordingly, sizes.

In addition, to increase efficiency, files with any graphic extensions are scanned - from to .png.

Rice. 11. Search for pictures using another version of DupeGuru.

12. ImageDupeless

Moreover, it is distributed free of charge and has a Russian interface. And the manufacturer periodically releases updates to it, increasing the efficiency of image search.

Rice. 12. Stylish interface of the ImageDupeless application.

13. Image Comparer

Especially if the user constantly downloads various information from the network.

Using utilities that detect duplicates, you can save more than one hour of your time and several gigabytes of disk space.

Many users are unaware of how many identical copies of files are stored on their hard drive. Meanwhile, they all take up space that could be used for something needed. If you are running out of space on your hard drive, then searching for duplicate files on your computer is one of the best ways to best solutions to clean it up a little.

You may have copies of files in a variety of formats stored on your computer: images, music, videos, or any other format. Such files can be stored in different directories and on different disks (if you have several of them). In addition, they may also differ in size or even extension. Therefore, searching for them by hand is a difficult and time-consuming task.

The best solution for finding duplicate files on your computer is special software. Now there are many different programs that search for and remove duplicate files, and they are all divided into two types: universal and focused on a specific type of data (music, images and video). The first option will allow you to quickly and easily remove duplicates of any format, however, compared to the second, it is much less accurate. So choose which one is preferable for you, and let's look at the most popular programs together.

Universal programs for finding duplicate files on your computer

As mentioned earlier, universal programs are capable of searching for duplicates of any format, but are inferior in accuracy to more targeted versions. There are two main parameters by which such programs compare files with each other: size and checksum. Although this approach increases search speed, it allows you to find only completely identical files, and not all of them. If you are satisfied with this option, then let's look at the most popular programs among Internet users.

Without exaggeration, the DupKiller program can be called the most popular in our homeland. And it’s not surprising, because it has quite a lot of advantages and practically no disadvantages. The first thing that captivates us with this program is, of course, complete and high-quality Russification. The second is the speed of work, it is very high here, and this despite the fact that the accuracy of the search here is pleasantly surprising. In addition to size and content, DupKiller also compares files by their modification date. The developers have not forgotten that the program is universal, and therefore it compares almost all currently existing file formats. Add to this a convenient interface and extensive customization of functions and you will understand why this program is so loved.

You can download it for free on the official website.

The Duplicate Finder program is not much inferior to the previous version and even has several individual advantages. Thus, the program not only finds similar files, but also sorts them. In addition to finding and deleting duplicate files, it also deletes empty folders and “null” files. The search here is carried out by size, checksum and file names.

Despite all this, the program is still not as popular among Russian users as DupKiller, although the main reason for this is most likely the lack of a Russian version of the program.

Glary Utilities

The third most popular program for finding duplicates on a computer is Glary Utilities. The peculiarity of this program is that it performs a number of different functions to speed up the PC: from cleaning the registry to managing security, and deleting identical files is just one of its many functions. The program is completely translated into Russian and is freely available. Its only drawback is the serious load it places on the system, which is why the computer can seriously freeze while the program is running.

Programs for finding copies of audio files

Programs for finding copies of audio files will definitely be useful to music lovers who store large amounts of music on their PC, and especially to those who like to download various collections of music, because such collections very often contain the same compositions. The statistics are that approximately every tenth audio recording from seasonal collections best music you already have on your PC. So consider this: if you have, for example, one hundred gigabytes of music on your PC, then at least ten of them are duplicates.

The situation is further complicated by the fact that such files may differ in both name and size. The only criterion by which such copies can be found is an audio track, which can be distinguished either by ear or by means of special programs. We will talk further about the best programs capable of finding duplicate audio files.

The best qualities of the Music Duplicate Remover program are its speed and search quality. The principle of its operation is that it listens to all audio recordings and remembers them, and then compares them with each other and looks for matches. Of course, this procedure takes much longer than checking universal programs, and therefore the speed here is fast only if you compare it with similar programs. The average scan time is about two hours per hundred gigabytes of files (which, by the way, is about three songs per second).

The Audio Comparer program is quite similar to the previous version, both in terms of the search principle and in terms of effectiveness. She is not inferior to her either in speed or accuracy. It is also worth mentioning that it has a kind of wizard that helps users understand the basic principles of the program when they are just starting to work with it.

Another program that deserves your attention is Dupe Guru Music Edition. Even the original version of the Dupe Guru program is quite competitive and boasts excellent speed and accuracy. But what is especially interesting is the small modification made by the developers in the Music Edition.

In the work of programs that search for duplicates, there is such a thing as “original file,” which means a file that will not be considered a copy and, after cleaning, will remain on your PC. Typically, the original is the file that was found before its copies; in rare cases it is given to the user to choose.

But Dupe Guru Music Edition, in addition to the usual comparison by sound, also makes a comparison by the quality of the audio file and, after completing the check, makes the original the file whose quality was higher than that of the others. That is, after deleting copies, you will only have the highest quality version of the composition on your PC.

Duplicate photo file search program

A large number of identical images in PC memory is also a very common problem among users. But at the same time, searching for identical pictures manually is almost the most difficult thing. In addition to the fact that the same images can be of different formats, resolutions or quality, they are usually not labeled, unlike the same video or audio files. Viewing and remembering all the pictures yourself, and then looking for copies in nameless lists is a thankless task, and therefore the help of a program that will search for duplicate files on the computer for you will be more useful than ever. Below are the most best programs search for duplicate photos on your computer.

Image Dupeless

The first program that will suit you for this purpose is Image Dupeless. This program will quickly find all similar images that are on your computer and offer you a detailed list of them with the ability to compare them with each other. The approximate time for checking this program is about half an hour per gigabyte of files (which in turn is about one thousand images of average quality).

The program is completely translated into Russian and is distributed free of charge on the Internet. At the same time, it is one of the easiest programs of this kind.

The Image Comparer application is shareware, which means you can download it without any investment, but you will have to pay extra to use certain functions. In terms of speed and size, the program is not inferior to Image Dupeless, but in addition it has several more advantages. Many users call the main advantage “a wizard for working with the program,” which helps you get comfortable “at first.”

However, what really looks interesting is the file verification procedure. The Image Comparer program will not only find copies of files, but will also set the percentage of their matches and even mark different places directly in the photo. This approach greatly simplifies checking for duplicates.

Based on all of the above, we can without a doubt call Image program Comparer is the easiest to use.

Once again the Dupe Guru program, but this time a slightly different version. Searching using Dupe Guru Picture Edition takes a little longer than using other applications, but the search quality is much higher. The program compares absolutely all images stored on your PC, regardless of their format, resolution or size.

Finding and removing duplicate video files on your computer

Here we come to the last type of duplicate files - video files. Of course, in order for identical films to appear on your computer, there must really be a lot of them, but in this case, even one copy will weigh up to several gigabytes, and therefore it is definitely worth checking. Several applications will help you with this.

Duplicate Video Search will allow you to find identical video files quickly and efficiently. It searches for copies based on video titles, sizes, and bitrates. In general, the program is nothing special, but it still has one interesting function in its arsenal.

We have already encountered the concept of “original file”, and now it’s time to remember it again. The fact is that the Duplicate Video Search program, just like Dupe Guru Music Edition, selects as the original file the one whose quality is the highest and it is the one that will remain on your computer after completing the search for duplicates.

Main plus Video programs Comparer is its speed. The program uses a rather interesting algorithm, in which it compares not the entire video, but only its individual fragments, which saves verification time.

The program also has disadvantages, for example the lack of Russian localization. However, thanks to the simple and understandable interface, this does not greatly affect the work process, and you can use the application on an intuitive level.

What really hinders the growth of the application’s popularity is the lack free version. What Video Comparer can offer you is a trial period of thirty days, and then you will have to pay 20 euros for further use of the program.

This concludes the article about finding duplicate files on your computer. As you can see, this procedure can hardly be called difficult, but it will allow you to free up quite a lot of space on your computer. Checking for duplicate files will never be superfluous, because, as mentioned earlier, many users do not even realize how many identical files they have before checking everything.
