7-Zip includes read support for .msi, cpio and xar, plus Apple's dmg/HFS disk images and the deb/.rpm package distribution formats; beta versions (9.07 onwards) have full support for the LZMA2-compressed .xz format. [51]

7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. [2] 7-Zip has its own archive format called 7z introduced in 2001, [12] but can read and write several others.
WinRAR is a trialware file archiver utility, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats, [ 6 ] and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive.
With some archivers (like RAR) the version of the software that is used greatly influences the performance values, both in speed and acquired compression ratio (not to mention platforms it was run on, both hardware and OS-wise, as these results may have been acquired on different platforms, there is no way to tell). --213.84.89.224 13:26, 4 ...
In 2010 Tom's Hardware benchmarks comparing it to the other popular archivers, FreeArc narrowly outperformed WinZip, 7-Zip, and WinRAR in its "best compression" mode. In the "default compression" tests, it lost to 7-Zip's LZMA2 , but still compressed better than WinRAR and WinZip.
On newer formats such as 7-zip, there is a solid block size option that allows for the concatenated data block to be split into individually-compressed smaller blocks, so that only a limited amount of data in the block must be processed in order to extract one file. Parameters control the maximum solid block window size, the number of files in ...
The LZMA implementation extracted from 7-Zip is available as LZMA SDK. It was originally dual-licensed under both the GNU LGPL and Common Public License , [ 12 ] with an additional special exception for linked binaries, but was placed by Igor Pavlov in the public domain on December 2, 2008, with the release of version 4.62.
