What is defragmentation? The best programs to defragment your hard drive on Windows

Surely every user at least once in his life has encountered the mysterious inscription defragmentation in the start menu and perhaps even thought about what it is needed for. More advanced users have some idea about it, but do not consider it necessary to use it.

So, disk defragmentation is a process during which, using special algorithms, the data on the hard disk is organized.

How does defragmentation occur and why is it needed?

Any user of a computer or laptop installs and uninstalls programs, as well as writes and erases various data, with a certain frequency. At the very beginning of using a new hard drive All data is stored sequentially, that is, data from one program is located next to each other. After any changes on the disk, new data begins to be written chaotically, that is, something ends up at the beginning, something at the end, and something ends up somewhere in the center.

Thus, when reading this data, the entire disk is searched, which reduces performance and costs time. During the defragmentation process, the system finds pieces of one file and places them as close to each other as possible, in addition, it transfers all data to the initial sectors of the hard drive, which again reduces the time for reading information.

The defragmentation process takes a long time, especially if it is performed infrequently. But after its completion, you can notice the system speeds up, data is copied faster, and you can also see an increase in performance in powerful 3D games. This is because the system does not need to search for data throughout the entire hard drive, because it is in one place.

There are many defragmentation programs available - one of them is a built-in tool, others are created by third-party manufacturers.

Programs for defragmentation

In official Windows programs You can find a built-in defragmenter, which is quite suitable for use, but it has a significant drawback. It cannot be used to efficiently carry out the procedure on a hard drive that is actively used. The native Windows program has weak algorithms that will help only novice computer users, as well as those people who do not store a lot of data on their hard drive. This program is not able to detect all the fragments and put them as close to each other as possible, so, as a rule, no special effect from its use is visible.

Defraggler is a powerful free defragmentation utility. Has powerful algorithms for searching and transferring data. Allows you to work sequentially with different logical drives or defragment the entire hard drive. An additional advantage is the ability to work in background, allowing the user to continue using the PC without compromising performance.

The program can be programmed to automatic shutdown after completion of work. Among other things, Defraggler provides the opportunity to conduct an analysis and draw conclusions about the feasibility of the procedure. Sometimes disk defragmentation is not at all necessary and the program will inform you about this. The defragmentation process is accompanied by a beautiful and visual graphic pattern in which multi-colored cubes form groups. The program has a simple and intuitive interface, so there should not be any problems using it.

O&O Defrag Free – shareware English-language utility. Free for home use. It is one of the most powerful at work. Conducts high-quality data defragmentation and does not take up a lot of resources. The program has a large number of settings and add-ons that are quite difficult to understand without knowledge English language. Able to work in the background. O&O Defrag Free is a great tool for confident users.

Small tricks related to disk defragmentation

In general, the need to defragment the disk arises due to the fact that most users operate their system incorrectly. Almost every hard drive is divided into at least two logical drives. Many believe that this is done so that if the system is reinstalled, important data remains intact, and this is partly correct. However, there is another reason for this division.

The user can fragment his hard drive quite independently without any programs. So, if it is known for certain that data will be stored on the hard drive for short-term use, frequent storage, and many programs will be installed, then it is best to make not two, but three or four logical drives.

The first, as you might guess, will be allocated for the system. You can install programs here, but it’s better to have a separate disk for them, because none of them are used forever, which means that old ones will be periodically deleted and new ones installed. It’s best not to touch the disk with the system at all, then you won’t have to do any defragmentation on it. The second disk should be reserved for long-term storage data, which will be added to but not deleted.

In this case, the data should be copied to it sequentially. For example, videos will come first, then music and then photos. File sizes also matter, because filling occurs from beginning to end, which means that smaller files should be placed at the end. In this case, this logical disk will also not require defragmentation.

The third disk will be dedicated to programs and sometimes you will have to use special programs. The last disk will be dedicated to temporary data. It can be combined with a software disc. This sequence was not chosen by chance. It turns out that permanent data will be recorded on the initial sectors, and those that are often deleted on the final ones.

If the hard drive is already full, then defragmentation can be done by copying everything from the hard drive, and then filling it back in, observing the order of the data and its size.

Watch the video for an even better description of the defragmentation process!

And this article will discuss the best programs for hard defragmentation disk. All of them are free, and you can easily find them at the office. developers website (links will be provided).

The developers themselves emphasize that Ashampoo Magical Defrag works quietly and unnoticeably, i.e. starts the defragmentation process only when almost all the resources of the computer or laptop are free. Therefore, you simply won’t notice any glitches or slowdowns.

Instead of a conclusion

Listed above are the top five free (or shareware) programs for defragmenting your hard drive. Therefore, if you do not like the built-in Windows defragmenter (or it does not work for certain reasons), install any utility. Links to them are given above, so you can easily install the program that you like the most.

Personally, I use IObit Smart Defrag. But this is just my opinion.

Good day!

Despite the fact that Windows has a built-in disk defragmenter, there are hundreds (if not more) of similar programs (that do it ten times better!).

The fact is that, in my opinion, Microsoft added it to Windows to have it, and its work is far from ideal (the algorithms are imperfect, there is no detailed schedule and settings, you cannot manually specify specific folders and files, etc.) ...

Addition!

If you don't know what defragmentation is and how to do it, I recommend reading this help article:

For additions on the topic - a special merci!

Disk defragmentation on Windows 7,8,10 is a mandatory and simple operation. Read on and see how it will help speed up your computer. Below are methods using built-in OS functions and third party utilities.

What is disk fragmentation and defragmentation?

Many Windows users You've probably heard that defragmenting your hard drive will speed up your computer. Let's take a closer look at what fragmentation and defragmentation mean and why you should start this process on your PC now.

Fragmentation is the breaking up of disk space into fragments. In simple words when on new HDD data is recorded, all information is divided sequentially (in clusters). After some time, the user copies, deletes, moves data. This provokes the release of space by some clusters and their replacement by others.

The data recorded on the disk can be distributed in “pieces” in different sectors of the drive. This usually happens with various executable files, videos and other media files. After deleting an object or moving it, the disk sector is freed. Over time, different types of information accumulate in neighboring sectors:

As a result, various types of data are scattered chaotically throughout the HDD. File reading slows down, which affects overall system performance. Also, a fragmented disk can cause deterioration in the performance of the hard drive.

You can fix the problem using the reverse process - defragmentation. The task of the operation is to compare all similar pieces of data and add them to common clusters. All hard data The disks are distributed “on shelves” and the HDD reading head becomes “easier” to find information.

What does disk defragmentation do?

• Programs and files open faster;
• Frees up space on your hard drive;
• Improves overall OS performance.

When and how often to defragment?

Disk defragmentation on Windows is a process that takes quite a long time. It should not be performed frequently, as it may negatively affect the operation of the hard drive.

The frequency of the process also depends on how often and how you use your computer. For example, if you constantly install new programs, download information, use disk space, defragment Windows disk recommended once every 1-2 months. This will allow you to maintain a good level of OS performance.

If you rarely launch games or applications, or do not store a large amount of data on the disk, you should run the process no more than once every 3-4 months.

Note that there is a concept of quick disk defragmentation on Windows. It works only “on the surface” of the HDD, that is, with those directories and partitions that you use most often. You can run such defragmentation using third-party utilities. They will run the operation every time you turn on the computer. This does not harm the device and keeps it running fast.

Defragmentation methods

You can start defragmenting hard disk partitions in two ways:

• Using Windows services;
• Using third party applications.

The first case is the safest, but takes a long time. Special programs allow you to defragment faster or run it every time you turn on the system. Before installing defragmenter utilities, we recommend scanning executable file antivirus.

Instructions for Windows 7, 8, 10

Defragmentation process:

Once the process is complete, close the command prompt and restart your computer.

Using the Defragger utility (free)

Defragger is convenient program to defragment the disk. Suitable for everyone Windows versions.

Immediately after launch, the utility will scan hard drives. To start defragmentation, select a disk from the list and click on the “Defrag” button at the bottom of the main window. Main feature application is the ability to visualize the process of reclaiming disk space.

The program is distributed free of charge. Other features of Defragger:

• Simultaneous scanning of multiple disks;
• Analysis of folders, files and individual applications;
• Choice of batch or regular optimization;
• Disk defragmentation in Russian. You can change the application interface language in the Settings tab.

AusLogics Disc Defrag (free)

Auslogics Disk Defrag is another popular free defragmentation program. Windows disk. With its help, you can simultaneously run defragmentation of several disks connected to the computer.

You can also set the priority for scanning and optimizing disks or set automatic defragmentation. If you are using old version Windows 7, we recommend checking the “Turn off PC after task complete” checkbox. As a rule, defragmentation of older versions of the OS can take several hours and it is better not to leave such a system turned on all night or while the user is away.

Diskeeper utility (paid)

Diskeeper is a paid defragmentation utility that offers more features and disk optimization options.

Program features:

• Accelerated data processing;
• Defragmentation without loading the operating system. This is possible thanks to the use of special program code algorithms;
• Generating reports on HDD operation and viewing the history of generating error reports;
• Automatic removal of temporary files and other “garbage” to speed up the operating system;
• Ability to optimize the operation of connected USB and CD drives;
• Troubleshoot defragmentation issues.

Why on SSD drives defragmentation cannot be done

If your computer works not with an HDD, but with an SDD, you do not need to perform defragmentation. File processing speed solid state drive does not depend on how the data is recorded on it.

We recommend disabling defragmentation for such drives. This can be done in the “Disk Optimization” window, the work with which is described in detail above. If you do not disable the process, the SSD will quickly fail, since such drives have a limit on the number of write cycles. Each defragmentation permanently overwrites partitions.

Solving defragmentation errors

If you are unable to run defragmentation or receive error messages while performing the task, follow these steps:

• Open command line on behalf of the system administrator;
• Enter the command CHKDSK /C (change the letter to the desired one);
• Press Enter to execute. The scan may take several minutes. As a result, a detailed report about the drive parameters and detected errors in its operation will appear on the screen. Error processing and resolution will begin automatically.

Also, a defragmentation error may appear due to lack of free space on the disk. We recommend deleting unnecessary files and applications, and then restart the process again. The HDD must have at least 1 GB of free space for normal operation.

Perform a scan file system antivirus or boot the OS into safe mode and try defragmenting again.

Another type of error does not manifest itself in stopping the process, but in the disappearance of files from the disk. This happens when multiple files are placed on the same cluster. The problem is typical for older versions of Windows 7. In this case, the system simply deletes all copies of files and frees up memory. It is impossible to return the data.

Bottom line

To constantly monitor the health of your hard drive, you should check the “Disk Optimization” window. Remember that the lower the percentage of fragmentation displayed in the window, the better the performance of your HDD. Also, before defragmenting the disk, scan it for errors using the “Analyze” button or using a third-party program.

Greetings friends! The topic of this article will be hard drive defragmentation. Mostly beginners do not know about this process, which is what causes the hard drive to fill with fragments.

On each hard drive of each computer user, thousands of files are saved and the same number are deleted. In their place, thousands of files are again installed, and then deleted with the same number.

Let me now try to explain this process in understandable human language.

Let's say you have bookshelves in your room. On each shelf all the books are sorted by name i.e. from a to z.

The hard drive is in the same condition without fragments. But one day, all the books were mixed up, the sorting order was disrupted and, ultimately, a complete house. The hard drive containing fragments is in approximately this state.

The newly purchased computer works with high speed and performance. Over time, the computer begins to slow down over time. In such situations, if you observe that the hard drive begins to crackle and operate noisily, this signals one thing, the time has come to perform defragmentation (reverse fragmentation)

Defragmenting a hard drive on Windows 7 is done in two ways:

Let's look at the first way to use the built-in program. This method has significant disadvantages. The process does not defragment some system files and the process itself takes a very long time.

Let's go start open all programs, then move on standard choose official Select the one that opens from the list disk defragmentation

Basically, in all cases, this partition is the system partition (the partition where the operating system windows).

After selecting, click Analyze disk. Once the analysis is complete, click Disk Defragmentation.

Defragment your hard drive with Auslogics Disk Defrag Free

This is a convenient free program that will help defragment your hard drive, while at the same time increasing the performance of your computer, which improves your performance.

This program has a number of advantages over analogues:

• Optimizes system windows files located on the hard drive to increase system speed.
• The developers have provided one feature that allows defragmentation of one folder or one file
• The program has a very useful idle mode that works automatically
• This program optimizes free space on your computer
• Flexibility in setting parameters hard drive defragmentation Convenient and intuitive interface

This program is being improved every month. In this article we will look at the version of the program

Auslogics Disk Defrag Free 5.4.0.0. The counter for this program has reached 11,000,000 users.

At the time of writing this article, this version of the program is only in English.

Auslogics Disk Defrag Free 5.4.0.0 can be downloaded from the official website.

When installing, no special knowledge or effort is required; we perform a normal installation. Launch the program

and preferably makes adjustments in the settings to improve the defragmentation result.

Let's go to settings(settings) open program settings(program settings) go algorithm ( algorithms ) . Next, insert a check mark in all items.

• Delete temporary files before defragmentation - this function allows you to clean your hard drive of debris stored on it,
• due to which it frees free space on disk. These files (garbage) are a sufficient number,
• to slow down the hard drive defragmentation process.
• Skip fragments larger than 10MB - fragments with such memory increases the reading time.
• Defragmenting such fragments does not provide any benefit except that it will only waste time.
• Move system files to the beginning of the disk - this function allows you to move those files forward
• on which the speed of the process and time depend. The structure of the hard drive is such that it has the highest speed
• readout is located at the beginning of the hard drive.
• Defragment in VVS - compatible mode - this feature prevents the growth of the VVS saving area,
• which occurs when moving files and reduces the risk of copying previous VVS data.

When setting these settings, the speed of the defragmentation process improves.

Hard drive defragmentation process

Open the program, select the partition, this is mainly the system partition (C), right-click and select Analyze (c).

After analysis, the program will reveal a map of the results and tell you whether defragmentation is necessary.

The red cubes on the map are fragments. If the message Advice defragment disks appears at the bottom of the results, this means that the program recommends defragmentation. And if there is no message, we leave everything as is; there is no limit on the number of fragments on the disk.

Basically if the result shows fragments less than 10% then state of hard disk is good.

The process takes from 5-15 minutes, it mainly depends on how many files are on your hard drive.

1. If you defragment your hard drive frequently, you will increase the wear and tear on the drive.
2. So I advise you to do defragmentation if necessary.
3. During the defragmentation process, leave the computer alone. Due to this, defragmentation time is reduced.
4. If for some reason you need a computer, you can use the program with the priority set to low.
5. To do this, go to settings, hover your mouse over defragment priority and select Low priority.
6. For the process to proceed normally, I recommend that the disk have 10% of the total memory free space

Scheduler defragmentation function.

There are times when your computer is always on. In this case, it is better to use a scheduler.

To enable the scheduler, go to settings(settings) click scheduler(Cluster Map).

Mark the section defragment automatic(Defragment automatically) ticked. Next we configure this function according to your conditions.

Example settings:

• When selecting the When PC is idle mode, select the time.
• Every day mode (daily) - set the time for daily checking.
• Weekly mode - set the day for defragmentation.
• Monthly mode - select the day and time to start the process.

If you install the scheduler on a laptop it will not work when using battery.

Attention: For the scheduler to work, the Auslogics Disk Defrag Free program must be in active mode, i.e. should be running.

In order for the program to start along with windows, go to settings(settings) select program settings(programm settings) and go to the tab general(general) check the box as in the picture.

That's all the question is: how to do it hard drive defragmentation reveal. If you have any questions, write comments. I hope the information was useful!
