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.
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
When comparing a LZMA 7z archive to a LZMA2 7z archive, for example, the decompression routines will differ. [citation needed] Several programs can create self-extracting archives. Among the Windows archivers are WinZip, WinRAR, 7-Zip, WinUHA, KGB Archiver, Make SFX, the built-in IExpress wizard, and others, including experimental ones.
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 ...
It handles encrypted *.7z, *.arj, *.lrz, *.rar and *.zip archives. Xarchiver uses the Direct Save Protocol XDS for drag and drop file saving. [14] The program acts as a front-end for various commonly installed libraries dealing with the supported compression formats. [15] [16] Xarchiver can't create archives whose archiver is not installed. [7]

In non-LZMA2 streams, lc must not be greater than 8, and lp and pb must not be greater than 4. In LZMA2 streams, (lc + lp) and pb must not be greater than 4. In the 7-zip LZMA file format, configuration is performed by a header containing the "properties" byte followed by the 32-bit little-endian dictionary size in bytes.
