The format's open architecture allows additional future compression methods to be added to the standard. 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.
