Archive 7 zip. Programs for Windows

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 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:

Is a file archiver with a high compression ratio for ZIP and GZIP formats, which is between 2 to 10% better than its peers, depending on the exact data tested. And 7-Zip boosts its very own 7z archive format that also offers a significantly higher compression ratio than its peers-up to 40% higher! This is mainly because 7-Zip uses , with strong compression settings and dictionary sizes , to slow but vastly improve density. If a zip tool gains its appeal from its ability to efficiently compress files, then 7-Zip proves it has a little bit o’ magic.

• Open architecture-The source code uses the GNU LGPL license, while the unRAR code is under a mixed license with GNU LGPL + unRAR restrictions.
• High compression ratio-Using its own 7z format with LZMA and LZMA2 compression, 7-Zip’s compression ratio is up to 40% higher than its peers. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10% better than PKZip and WinZip.
• Strong AES-256 encryption-This includes both password protection of files and encryption of file names.
• Ability to use may compression, conversion, or encryption methods-For example 7-Zip:

• Powerful file manager and command line versions-There’s also a plugin for FAR Manager.
• Localizations for 79 languages-This kind of support is why 7-Zip is the world’s favorite free compression software.

Pros	Cons
7-Zip is easy to download and use, it opens and compresses most everything, and is has a Windows shell extension.	The interface is a little sparse and so are the instructions, but the program works like a charm anyway.

Main features of 7-Zip

• select any file (or several files and folders) on your computer through the file manager window and create an archive from it;
• When creating an archive, you can specify its compression level and select its format. By default, 7z is selected, 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 using a password;
• The creation of multi-volume archives is supported (the size is selected before creation from a given list) and self-extracting (SFX) archives. That is, archives that do not require an archiver to extract, they have an EXE extension;
• you can add your comment to any file through the 7-Zip menu (or by pressing the key combination CTRL+Z);
