Bzip2 – The standard Burrows–Wheeler transform algorithm. LZMA2 – modified version of LZMA providing better multithreading support and less expansion of incompressible data. The LZ stage is followed by entropy coding using a Markov chain-based range coder and binary trees. LZMA – A variation of the LZ77 algorithm, using a sliding dictionary up to 4 GB in length for duplicate string elimination. The following compression methods are currently defined: The format's open architecture allows additional future compression methods to be added to the standard. #Spam with a .7z file extension archive
to re-assemble an archive from a set of multi-part component files).
Support for multi-part archives : e.g. Compression and encryption of archive headers. Support for solid compression, where multiple files of like type are compressed within a single stream, in order to exploit the combined redundancy inherent in similar files. Large file support (up to approximately 16 exbibytes, or 2 64 bytes). High compression ratios (depending on the compression method used). Open, modular architecture that allows any compression, conversion, or encryption method to be stacked. 
The 7z format provides the following main features: There have been additional third-party attempts at writing more concrete documentation based on the released code.

The specification can be found in plain text format in the 'doc' sub-directory of the source code distribution. The official, informal 7z file format specification is distributed with 7-Zip's source code since 2015. The latest stable version of 7-Zip and LZMA SDK is version 22.01. The LZMA SDK 4.62 was placed in the public domain in December 2008. The 7-Zip program is publicly available under the terms of the GNU Lesser General Public License. The 7z format initially appeared as implemented by the 7-Zip archiver. Yes: GNU Lesser General Public License / Public domainħz is a compressed archive file format that supports several different data compression, encryption and pre-processing algorithms.
