The best Hex editors, calculators and converters. So what to choose
HxD Hex Editor is a convenient hexadecimal editor that has a good set of functions, and, on top of that, is free. The program allows you to work with files of any size without any difficulty, subject to modifications RAM. That is, it is possible to edit not only those files that are on the hard drive, but directly from the RAM. It is impossible not to mention the speed of this program. HxD has very high performance. Regardless of the file size, the utility opens it almost instantly. All operations (replacing, searching, copying and exporting data) are performed quickly. There are also many other functions, such as splitting and merging files, creating statistics and bookmarks, permanent secure deletion, filling according to a selected template, inserting bytes, and so on.
The HxD editor is very well thought out. It took into account everything that is needed when editing files. You can exchange files with other applications. This set of features is provided free of charge. The program is Russian, but other languages can be selected. It should also be noted that the program does not limit the number of “cancellations” of the last action.
This article will talk about working in the free hex editor Free Hex Editor Neo, using the example of editing a file BkEnd.dll from the delivery for correct operation of this system with .
1. A little about hex editors and files
As you know, any file stored on a computer’s hard drive is a sequence of machine words - bytes. A byte, in turn, consists of 8 bits, each of which can take the value “0” or “1”, which means that one byte can take 2 8 = 256 values in the range from 0 to 255. The number is 256 10. written in the hexadecimal system, is a round three-digit number - 100 16, i.e., to represent any number from the range 0-255, no more than 2 digits will be required. This means that it is very convenient to write the value of each byte as a two-digit number in the hexadecimal number system.
The hex-editor shows us the file the way the machine “sees” it, namely, as a sequence of bytes. For example, opening a file in an editor, we will see a matrix consisting of 16 columns and the number of rows depending on the file size. Each matrix value corresponds to one byte, written in two-digit hexadecimal number. By changing the value of the desired byte, we can, accordingly, change the file itself.
In addition, next to the table we can see:
- To the left of the matrix a line of numbers is displayed: each line corresponds to a number indicating the address/offset of the first byte of this line. The address step is equal to the number of columns.
- Another ruler is displayed at the top of the matrix: above each column the offset of the byte in this column relative to the first byte of the corresponding line is displayed. The sum of the number corresponding to the i -th row and the number corresponding to the j -th column is the address/offset of the byte (i;j) located at the intersection of the taken row and the taken column.
- To the right of the matrix the same data is displayed, but in a different interpretation. The most common alternative is to display data as ASCII text, with bytes whose values correspond to non-printable characters displayed as dots (·). You can also edit values in this area.

For example, I need a byte with an offset 000d9cca write value eb. To do this, I find the row “000d9cco” and column “0a”, double-click on the desired cell and enter a new value.
Proceeding similarly, I make the following changes:
- To fix the error " MS required SQL Server 6.5 + Service Pack 5a or higher!» change the fields:
by offset 000d9cca meaning 83 change to eb
by offset 000d9ccb meaning e8 change to 15
by offset 000db130 meaning 83 change to eb
by offset 000db131 meaning e8 change to 10 - To fix the error " The sort order set for the database differs from the system one!»:
by offset 0018a79d meaning 75 change to eb - To fix the error " Incorrect syntax about keyword"TRANSACTION»
Phrase DUMP TRANSACTION %s WITH TRUNCATE_ONLY, which is located at the offset 002856B0 replace with a phrase ALTER DATABASE %s SET RECOVERY SIMPLE - To fix the error " The database cannot be opened in single-user mode", change the fields:
by offset 0028549c meaning 64 change to 6b
by offset 0028549d meaning 62 change to 70
After all changes are made, save the file by clicking " File» — « Save» .

Description
This is a program designed for editing files on the hard drive and working with RAM. Hex Editor is available in free version and convenient to use. Its difference from standard editor is that the files are in hexadecimal format. Thanks to this program, you can demonstrate not only the content, but also various service information. By reading it, users can independently understand that there is no malicious code, and the state of the object becomes more clear.
The application contains the most current features of the standard editor. It is used to replace, view, change, copy and retrieve information from different parts of the device’s memory. Each user has the right to equip files program code, study files with a small extension and correct them at will. You can also download HxD Hex Editor 1.7 7.0 rus to your computer from our website.
Program design
Like many popular editors, Hex Editor has a simple design. The program has floating panels and convenient tabs. Files used for editing can be opened horizontally or vertically. Also included in the tools are different types encodings, which makes the editing process more interesting. To get acquainted with the main advantages of the program, you need to download Hex Editor HxDxd in Russian for free.

Now there will be a lot of material on the topic of what data consists of and how it can be edited. Many people know that any file on a computer (picture, text or multimedia) is a binary code - zeros and ones. To edit such files, HEX editors are used - an application that edits data consisting of byte code. Bytes in the editor are represented in hexadecimal format.
File extension
The problem is the huge number of file types and at first it is not clear how operating system defines text, multimedia or archive and other types of data. As you know, the system identifies a file using an extension added after the name, for example, “.exe”, “.txt” and others.
The settings in the OS are flexible, which means the extension of any file can be deleted, but then the operating system will not be able to open it, it will not understand which program to launch it with. In this case, the logical structure of the object will not change. The image shows text file, and next to it is the same thing, but without an extension and its icon is white.
If an object without an extension is still the same file with a logical character set, then the extension does not determine its type, but then what? There is such a thing as a format - this determines the type, and it is also a specification of the data structure. Expansion is a completely different term. What to do if the user initially came across a file without an extension, but urgently needs to open it, and with what is unknown?
Descriptors
All files can be roughly divided into two components - a header, which contains object identification data, and various metadata. The second component is the “body” of the object, with the help of which the type of the object and parts of the header, which has the name of the descriptor, are determined. Two popular descriptors are ASCII and HEX. The second option is analyzed using the editors mentioned at the beginning.
The first ASCII method is defined using text editor, for example, Notepad++, however, it is worth considering one point - some sets of bytes cannot be converted to ASCII format, which means it is recommended to use HEX editors. By launching any file using such a utility, the window will display a matrix view with a sequence of bytes, where one byte is contained in one of the cells. Information about the descriptor is usually found in the first 3 cells, rarely in more quantities. Cells are counted horizontally. The data displayed in the cells is presented in hexadecimal code.
Decryption of the descriptor
To understand what kind of data is there, you need to decipher the code. To do this, you will need a special service that determines file formats, for example, open-file.ru. But there are other resources that are easy to find on the Internet. After uploading the file to the site, the data will be analyzed and then the result will be displayed. A table with the type, format and description of the file will appear below.
What we discussed above is the use of HEX editors. Now let's understand the ASCII code. This code can be analyzed using the same open-file.ru. In other words, both codes are checked on the resource and nothing actually needs to be entered.
Sometimes the format is not so easy to determine. This applies to ASCII headers. The fact is that the first few characters may be related to file extensions, and maybe to several formats.
Of course, there is an option to define the format. Multiple rows will be used for analysis rather than just one. Then some of the elements located there will, in any case, indicate the type of the object.
What else can you do with the HEX editor
In addition to the fact that HEX editors help analyze any file, it is possible to:
- work with disk images;
- edit sections;
- change the contents of RAM;
- change the virtual address space of the process, etc.
For example, utilities of this type are used in software development. When you need to enter data after compiling the program, but you don’t want to recompile it. Any program code can be changed using a HEX editor. Of course, you need to be able to do this and find the necessary data. In this way, they seek to correct errors in the code, or use it for hacking and cheating. This means that HEX editors are widely used.
Which HEX editors to use
There are many programs for editing data, and here they are presented below:
Popular utility for Windows. Using it, the user will not be able to open any type of file and change it. If something is edited incorrectly, the utility has a history of changes and you can always return to the original state.
The tool works very quickly, does not weigh much, and is capable of working with large files. The interface is simple and suitable for beginners, there is a Russian language.
This editor can be used in the demo version for a while, and then you need to purchase it. The tool is universal, where many interesting options are found.
It is possible to work not only with files, but also with hard drives, flash media, optical disks and even floppy disks. All file files are supported Windows systems. Supports partition cloning and complete removal data beyond recovery
If you are a beginner, then this program will be enough for you, especially since in the Help section there is an option to switch to the Russian-language interface.
The utility is 2 in 1, as it has a file comparison function and a built-in HEX editor. Sometimes you may need to compare these files to determine differences and similarities, and analyze the structure of objects in different formats.
If there is a difference in two files, the areas on the matrix will be painted in a certain color, and the comparison itself takes place in a matter of seconds. However, files no larger than 4 GB are suitable for analysis.
The utility itself has the ability to change the interface. Which means the user can customize it for himself. The work will happen faster.
This thing comes free, but it can work with large data of any formats and encodings. It is possible to change the RAM and hard drive.
The program combines hexadecimal code output and ASCII text output. The interface for the English interface is quite simple, so working with it will not be difficult, especially if you have already worked in similar editors.
If a file does not open in one editor, then it will open in this one. That's why I've given here a list of several utilities. The specified tool is responsible for opening binary files. There are a lot of settings, but system requirements available for any computer.
Working in this editor is as simple as printing in Word. There are options for comparing files, their checksums and exporting analysis to various formats, such as html.
If you need to convert one code to another number system, then Hex Workshop has a converter. The program is shareware, which can be considered one of the disadvantages.
Now you have learned what HEX editors are and why they are used. In the future I will try to write articles on working with them, for example, when you need to edit a file.
