Download the program to your computer 7 zip. Programs for Windows. Extracting files from an archive

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

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

Features of the 7-Zip archiver

When compressing files in 7-Zip, several threads are used simultaneously, which greatly speeds up this process. So, for example, when archiving to 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 one, it is much higher than that of the latter. You can download 7-Zip in Russian for free from our website.

With 7-Zip, you can archive and unpack files in almost all popular 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.

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

7-Zip has been developed 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 limitations.

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 streams simultaneously. For the LZMA compression algorithm, the archiver can use up to 2 streams at the same time. The impossibility of using more of them is explained by the sequential nature of continuous compression. The LZMA2 compression algorithm does not have this disadvantage.

When compressing in 7z format, special filters-normalizers are also used. So, 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 some media types, such as uncompressed 24-bit images.

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

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 has been 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 system 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

7-Zip is a free file archiver that offers a high compression ratio. The program is an analogue of the popular WinRAR, however, it is distributed absolutely free of charge.

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 versatile. 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 7z, ZIP, BZIP2, GZIP, TAR files (packs / unpacks) and RAR, RPM, ARJ, LZH, CAB, Z, CPIO, CHM, DEB ( unpacks).

The 7-Zip program supports AES 256-bit encryption and can work with such popular archives as RAR (including RAR3 and CAB), ZIP.

The 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 7z format;
when 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;
encryption of archives;
the presence of a built-in file manager;
integration into the shell of the Windows operating system;
the presence of a plugin for the FAR Manager and Total Commander programs;
powerful command line support;
multilingual interface 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 “squeezes” files into the 7z format. This free archiver differs from its “competitor colleagues” WinRAR and WinZIP by 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 “strong 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 features. 7-Zip works with a large number of archive formats and contains such handy tools as updating and splitting modes (splitting).

I think every computer user should download 7-Zip for free, since the program is really indispensable 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 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 you can restore it using, 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 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: 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.

7-Zip is the latest version of a free and powerful file archiver for Windows. This archiver, despite the fact that it is a free open source product and distributed under the GNU LGPL license (with the exception of the unRAR decompressor code, which has license restrictions), thanks to its own 7z format, it surpasses even such popular commercial archiver programs in terms of data compression , as well as .

7-Zip is a reliable, time-tested archiver program that uses various algorithms and works with a huge number of formats, both for creating archives and for extracting data.

The following algorithms are supported:

LZMA2, LZMA, Bzip2, PPMd and Deflate

7 - zip works with the following data formats:

Compression and decompression: 7z, BZIP2 (TBZ, TBZ2, TB2, BZ2), GZIP (TGZ, GZ), ZIP (JAR), TAR, XZ;

Data recovery only (decompression): CAB, ARJ, CPIO, DMG, CHM, CramFS, DEB, MBR, FAT, HFS, ISO, LZMA, LZH (LHA), NSIS, NTFS, MBR, MSI, RAR, SquashFS, UDF, RPM, VHD, Z (TAZ), XAR.

However, it is still worth noting that the highlight of this archiver, perhaps, is the presence of its proprietary compression format - .7z, which uses its own highly efficient data compression algorithm LZMA2 \ LZMA (Lempel Ziv Markov Algorithm). Compared, for example, with such a popular compression format as .zip, the compression ratio of the 7-Zip archiver into its own data packaging format. 7z is an order of magnitude higher than that of the same popular WinRAR and WinZip, which is achieved through the use of various normalizing converters and filters, which, together with the possibility of using 7zip for free, is undoubtedly a weighty argument in favor of using this particular archiver.

7Zip has an extremely minimalistic interface (which is not the most important thing for programs with similar functionality), the program can be easily configured and used from the explorer context menu, choosing the most needed functions for everyday tasks.

If you are looking for a free, simple, and at the same time powerful archiver, then in this case, 7-zip is the best fit.
