7-Zip is a world famous free archiver with free source code. The utility is compatible with almost all known archive formats. Plus, it has a built-in manager as a convenient shell. Command line control is also provided.

The manager has a function for testing files. When it is activated, the number of files and the total size of the archive (in its original and compressed states) are displayed. It also shows the number of errors found if the file suddenly becomes corrupted. In this case, the user will not be able to open the archive, but it can be restored using ZIP Recovery Toolbox, RAR Recovery Toolbox or similar programs. But some zip archives cannot be opened due to bad headers (wrong file encoding). In this case, it is better to use UnZip Me or WinRAR.

The program is very easy to use. It is not necessary to run it to unpack or pack a file - just right-click on the desired file and select the desired action.

7-Zip has already stood the test of time: the developers have been working on improving the utility for more than 15 years. During this time, the archiver has gained wide popularity and has become one of the most useful programs for various platforms.

Key features and functions

• the utility uses different data compression algorithms to get the best option;
• the program runs faster on multi-core processors thanks to the multi-threaded compression mechanism, and also supports 64-bit operating systems;
• work with all popular archive formats like CAB, GZIP, TBZ, TAR, ISO or RAR (besides the main 7z and ZIP);
вЂў the ability to test the power of your computer through the option "Performance Testing" (Benchmark);
• ability to add comments to archives and verify checksums;
• integrates into popular file managers (Total Commander, Far Manager) as a plugin;
• registration is not required;
• can be used for data recovery in combination with FreeFileSync;
• support for block encryption algorithm AES-256;
• support for all operations for continuous archives.

What's new in this version?

• Fixed problems with the program installer on Windows Vista, due to which it did not create links in the start menu;
• Fixed several bugs in the RAR code.

The program comes in two versions: without a graphical interface, for command line use, and with a graphical shell. The interface of the archiver is made in a minimalist style and does not contain bright icons or eye-catching fonts.

The program supports algorithms: PPMd, Deflate64, Bzip2, LZMA2, Deflate and LZMA. There are 14 archive formats available for data packaging, and support for unpacking is implemented for 25 formats. The native .7z format uses an advanced algorithm, resulting in a higher compression ratio than competing software. The following functions are also available in the program:

• Creation of self-extracting archives. Actual for .7z format;
• Creation of multivolume .7z archives;
• Hardware acceleration, which allows you to significantly speed up the program;
• Creation of encrypted archives;
• Computer performance testing;
• Unicode support.

The application is released in separate versions for 32-bit and 64-bit operating systems. When working with archives, the application can use up to 8 threads simultaneously, inclusive. Multithreading depends on the compression algorithm used, for example, for LZMA it is only 2 simultaneous threads. The compression ratio itself directly depends on the data being compressed: under equal conditions, an archive in .7z can be up to 25% smaller than when the same data is compressed in .zip. The archiver has a built-in file manager with the ability to work in two-window mode, which greatly simplifies the work with archives.

Working with the program is very easy. In order to create an archive of a file or folder, you only need to select the object and, after pressing the right mouse button, select the appropriate action item in the menu. The program can calculate checksums, which will be convenient for checking the integrity of downloaded archives. Useful users will be the Benchmark function, which checks the performance of the computer.

Some features of 7-Zip: very high compression ratio in 7z format, ability to create self-extracting archives for 7z format, ability to encrypt archives, built-in file manager, Windows shell integration, plug-in for FAR Manager, plug-in for Total Commander, powerful version for command line, multilingual interface.

7-zip is a very famous product of Ukrainian developers that works with various archive formats. The source code of the utility is open and it can be freely used for both personal and commercial purposes. A distinctive feature of this archiver is its high functionality and good compression performance. 7-zip is one of the most "compressing" programs in its class. In addition to the very efficient native 7z format (up to 30-70% better compression than the classic formats), the program also works well with the common zip format, compressing files 2-10% better. The interface, which is absolutely standard for the archiver, is complemented by the following functions and capabilities:

7-Zip is a free, constantly updated classic archiver for Windows, whose appearance is reminiscent of the previously popular file managers. Its main window is divided into 2 parts, in each of which you can navigate through the folders on your computer and, in addition to operations with archives, copy, move and delete ordinary files.

You can use 7-Zip for any purpose (even on computers of commercial organizations) completely free of charge, it is completely free software, one of the few that has such a status today.

Installing 7-Zip deserves special attention - it is so simple that even a grandmother can handle it. In the small window of the installer, just click one button "Install", and the archiver will then appear on your computer.

• select any file (or several files and folders) on the computer through the file manager window and create an archive from it;
• When creating an archive, you can specify the degree of compression and choose its format. 7z is selected by default, but bzip2, gzip, tar, wim, xz and zip are also available for creation;
• 7-Zip supports opening archives of most modern formats, including the RAR format;
• created archives can be encrypted with a password;
• supports the creation of multi-volume archives (the size is selected before its creation from a specified list) and self-extracting (SFX) archives. That is, archives that do not require an archiver to extract, they have the EXE extension;
• you can add your own comment to any file through the 7-Zip menu (or by pressing the CTRL + Z key combination);
• Among the additional features that are not directly related to working with archives, we can mention the calculation of file checksums;

7-zip is a program for archiving and unpacking files. Works with almost all compression formats, has its own extension - 7z. It is based on highly efficient archiving algorithms.

7-Zip allows you to create archives and split them into parts / volumes of a specified size, for example, you can split a 1 GB file into 5 smaller ones of 200 MB each. In addition, when creating an archive, we can choose the compression level and algorithm, the higher the level, the more resource-consuming the compression process will be, and as a result, the smaller archive weight.

An interesting feature of the program is the creation of self-extracting SFX archives, and the ability to protect archives with a password. It also supports the integration of basic commands into the context menu of the windows operating system and the execution of commands through the cmd command line.

The interface is simple, but offers easy access to the most important functions and supports Russian out of the box. Less experienced users can easily master the basic operations for comfortable work.
