Download 7 zip latest version. Programs for Windows. Its own unique extension
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.

Download a free archiver with its own 7Z format
Open Source Windows
7-Zip is a completely free archiver that is valuable for its own 7z format. This format is capable of achieving a very high compression ratio and is ideal for archiving large amounts of information (for example, large programs or games). In addition, 7-Zip supports all other popular archiving formats: ZIP, RAR, GZIP, ISO, LZH, LZMA, ARJ, BZIP2, CAB, CHM, CPIO, DEB, DMG, HFS, MSI, NSIS, RPM, TAR, UDF, WIM, XAR and Z.
The developer, as well as independent testers, note that the compression quality of ZIP and GZIP formats in this program is slightly higher than in most others. It remains to be noted that the program has a very simple and user-friendly interface without any decorations or frills.
Although this release is a beta release, it is quite stable and suitable for everyday use. In the development cycle of the 7-Zip archiver, final releases rarely appear, and test versions most often function without any problems.
Attention! In the Russian segment of the network, access to the site and downloading the 7-Zip distribution kit is blocked.
What's new in 7-Zip 20.00 Alpha:

7-Zip is a free file archiver that offers a high compression ratio. The program is an analogue of the popular WinRAR, but is distributed absolutely free.
The 7-Zip archiver is easy and simple to use. Its intuitive and user-friendly interface has been translated into 60 languages, which makes the program quite universal. One of the main advantages of 7-Zip is that the archiver has a powerful file manager, a plugin for FAR Manager. The program can be built into Windows Explorer and self-extract 7z archives.
Among other things, 7-Zip has a high compression ratio and works with files 7z, ZIP, BZIP2, GZIP, TAR (packs/unpacks) and archives of RAR, RPM, ARJ, LZH, CAB, Z, CPIO, CHM, DEB formats ( unpacks).
The 7-Zip program supports AES 256-bit encryption and can work with such popular archives as RAR (including RAR3 and CAB), ZIP.
Main characteristics of the 7-Zip archiver:
- the program supports the following formats: 7z, ZIP, MSI, CAB, RPM, Z, DEB, LZH, NSIS, RAR, ARJ, CHM, WIM, GZIP, BZIP2, CPIO, ISO, TAR and RPM;
- 7-Zip offers a very high compression ratio in the 7z format;
- working with ZIP GZIP formats, you get a compression ratio 2-10 percent higher than in WinZip and PKZip;
- creation of self-extracting archives for 7z format;
- archive encryption;
- presence of a built-in file manager;
- integration into the Windows operating system shell;
- availability of a plugin for the FAR Manager and Total Commander programs;
- powerful command line support;
- The multilingual interface also includes Russian.
The 7-Zip application is a serious player in the world of archivers, whose main trump card is its own LZMA algorithm, which “compresses” files into the 7z format. This free archiver differs from its “competitor colleagues” WinRAR and WinZIP in its slower operation, while the “lower” speed is easily compensated by a much higher compression ratio. As a result, 7-Zip is great for working with giant files, and this “strongman archiver” can work 30% more efficiently than its faster competitors.
At the same time, 7-Zip is not as secure as WinZIP or WinRAR due to the lack of a virus scanner, but this program has no less capabilities. 7-Zip works with a large number of archive formats and contains such convenient tools as update and splitting modes.
I think every computer user should download 7-Zip for free, since the program is truly irreplaceable and also has a free status.
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 file testing function. When activated, the number of files and the total size of the archive (in original and compressed states) are displayed. The number of errors found is also shown if the file suddenly turns out to be damaged. In this case, the user will not be able to open the archive, but it can be restored using or similar programs. But some zip archives cannot be opened due to incorrect headers (incorrect file encoding). In this case, it is better to use or.
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: developers continue to work on improving the utility for more than 15 years. During this time, the archiver gained wide popularity and became one of the most useful programs for various platforms.
