7-Zip– popular free archiver allowing compress data to reduce the occupied volume. A tool like this is necessary on every device and is especially relevant when you need to transfer large files over the Internet.

Why do you need to download 7-Zip?

The 7-Zip program is characterized by a high level of file compression, support for well-known formats and the ability to protect archives with a password. The 7 zip archiver features free source code, which, thanks to an open license, is used in a number of other common products with similar functionality. Therefore you can download 7 zip for free and use it without restrictions both on home devices and on computers of commercial organizations.

The archiver was developed back in 1999, since then it has been continuously improved and today occupies a leading position among analogues in terms of the level and speed of data compression. 7 zip is capable of working with many common data formats.

Its own unique extension

Thanks to the special LZMA compression algorithm, the 7 Zip archiver has its own unique 7z format. This format, according to experts, has maximum compression ratio and is ideal for archiving significant amounts of information (large games, programs, etc.). The product has an extremely simple and easy-to-learn interface, does not contain advertising, supports many languages, which allows you to download Russian version 7 zip.

Integration with Windows and programs

After downloading the archiver and installing it, it integrates into the conductor operating system, as well as the most popular file managers (Total Commander, FAR Manager) in the form of a plugin. This allows you to perform operations with archives without launching the program itself.

The 7-zip archiver has the following advantages:

Capable of packing and unpacking most known formats, for which you need to download the free 7 zip archiver;
High compression ratio, especially for the native 7 zip format (for example, compression in the zip format is 2-10% better than in similar programs; and in 7-Zip it is 30-70% better than in ZIP).
The ability to archive in multiple threads, separately for each file, which significantly speeds up the compression process.
Formation support self-extracting SFX archives for 7z format.
The ability to encrypt data using the advanced AES-256 algorithm and protect archives with a password for 7z and ZIP formats.
Testing system performance during archiving using a special built-in utility.

Using 7-Zip multi-threaded mode Significantly improves process efficiency and performance for devices with multi-core processors running 64-bit OS. For such systems, a separate version has been developed, for installation of which you need to download 7 zip 64 bit.

The disadvantages of the program include:

Inability to view and extract files if the archive is incomplete or damaged;
Inability to save information about file access rights.

The archiver is designed specifically for Windows OS(with support for all other versions), in particular, we recommend downloading 7 zip for windows 7. The archiver works on smartphones, laptops and embedded systems running Windows CE. There is also ported version for command line Linux/Unix.

7Zip- the best free archiver. It has excellent operating speed and stronger information compression (compared to WinZip and Winrar).
7-zip is a cross-platform program, i.e. Works on all operating systems, including the Windows 7, 8, 10 family.
After the appearance of this archiver, most games (and games are the worst compressed) began to be packaged in the 7z format. This speaks volumes about the quality of the program. Since the archiver is completely free, it can be downloaded and used on office computers.

Program installation

Installation is quite simple, you need to download the 7-zip 32 bit or 64 bit program from the official website or below on this page. Start the installation and click “Next” a couple of times. All. No keys or registration. Now, by right-clicking on the file, the “7-zip” menu item will appear - you can archive, unpack, etc.

You also need to associate the archives with the program. Launch "7-Zip File Manager" - Tools - Settings - "Select All" - "OK", now all archives will open automatically.

7-Zip is a free file archiver with a high degree of data compression. Supports multiple compression algorithms and multiple data formats, including the proprietary 7z format with the highly efficient LZMA compression algorithm.

7-Zip has been in development since 1999 and is free and open source, most of which is freely distributed under the terms of the GNU Lesser General Public License, with the exception of the unRAR decompressor code, which has restrictions.

7-Zip uses multithreading and allows you to use a different number of threads for compression, depending on the algorithm or format. When creating archives in which files can be compressed independently of each other (for example, ZIP), the program can use up to 8 threads simultaneously. For the LZMA compression algorithm, the archiver can use up to 2 streams simultaneously. The impossibility of using more of them is explained by the sequential nature of continuous compression. The LZMA2 compression algorithm does not have this drawback.

When compressing in the 7z format, special normalizer filters are also used. Thus, for more optimal compression of 32-bit x86 code, normalizing converters BCJ and BCJ2 are used. 7-Zip also has an optimizing delta converter for certain types of multimedia data, such as uncompressed 24-bit images.

Compression results are highly dependent on the data being compressed. Typically 7-Zip compresses the 7z format 4-25% better than the ZIP format.

The main platform is Microsoft Windows (including Microsoft Windows CE), where two versions of the program are available: with a graphical interface and a command line version. The console version was ported by the developer community to POSIX systems under the general name p7zip. Ported versions for other systems, as well as the original 7-ZIP program, are available on the SourceForge website (as of November 7, 2010, the program has been downloaded from the site more than 109 million times).

7-Zip is the winner of the 2007 Community Choice Awards for Best Project and Best Technical Design.

Key Features of 7-Zip

Supported algorithms:

Supported formats:

In addition to archiving itself, 7Zip can encrypt compressed data. For this, a reliable 256-bit AES encryption algorithm is used. The program is free to download and is distributed as open source. Download 7Zip free for windows 7. The program has a simple Russified graphical user interface.

Creating an archive

7z archiver supports several data archiving formats, so it is possible to select the required archive format. By default, the program uses its own format – 7z. It is this that provides the best compression quality. ZIP and TAR formats can also be used.

If you need to restrict access to the archive, you can protect its contents with a password. To ensure a higher degree of data protection, the program can encrypt file names, which will not allow you to guess their contents by name.

Extracting files from an archive

To extract files from an archive, you need to select the desired archive or file in the archive in the main window of the 7Zip program and use the button Extract or the menu command file 7 –zip Unpack (if instead of the Unpack command you select Unzip here, the program will automatically unpack the archive into the current folder)

Performance test

7Zip contains a built-in test of computer performance when archiving data. To run the test, you must use the menu item Service - Performance testing. After selecting this menu item, the PC testing window will appear. By default, the program itself correctly determines the number of cores and threads in your installed processor. The developers of 7Zip for Windows 7 recommend running a performance test immediately after installing the program in order to be sure of its functionality on this computer.

7-Zip is a free archiver program in Russian for unpacking or compressing files on Windows. It was developed in 1999, and has now become one of the leaders among similar products. In 2007, in a specialized competition SourceForge Community Choice Awards it received awards in two prestigious categories for best project and best technical design. You can download 7-Zip for free on this page.

The program is developed for Windows and is supported by all its versions, including Windows CE - the operating system for smartphones, laptops and embedded systems. Runs either graphically or using the command line.

Features of the 7-Zip archiver

When compressing files in 7-Zip, multiple threads are used simultaneously, which significantly speeds up the process. For example, when archiving in zip format, up to eight streams are used simultaneously. That is why this program is ahead of many of its competitors in terms of file archiving speed. For example, on a computer with a single core processor the compression speed is almost identical to WinRAR, and on a dual core processor it is significantly higher than the latter. You can download 7-Zip in Russian for free from our website.

With 7-Zip you can zip and unzip files in almost all popular file formats: 7z, WIM, TB2, BZIP2, BZ2, GZIP, TBZ, TAR, JAR, GZ, TBZ2, XZ, ZIP and TGZ. In addition, the program easily unpacks (but does not pack) other formats: ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, MBR, ISO, LZH (LHA), LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, XAR, Z (TAZ). By the way, this archiver compresses ZIP and GZIP formats 10% better than WinZip. And the 7z format is 25% better than ZIP, which is already a good advantage.
