7z

7z is a compressed archive file format that supports several different data compression, encryption and pre-processing algorithms. The 7z format initially appeared as implemented by the 7-Zip archiver. The 7-Zip program is publicly available under the terms of the GNU Lesser General Public License. The LZMA SDK 4.62 was placed in the public domain in December 2008. The latest stable version of 7-Zip and LZMA SDK is version 15.12.〔
The official 7z file format specification is distributed with 7-Zip's source code. The specification can be found in plain text format in the 'doc' sub-directory of the source code distribution.
== Features and enhancements ==
The 7z format provides the following main features:
* Open, modular architecture which allows any compression, conversion, or encryption method to be stacked.
* High compression ratios (depending on the compression method used)
* Rijndael/AES-256 encryption.
* Large file support (up to approximately 16 exbibytes).
* Unicode file names
* 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.
* Compression and encryption of archive headers.
* Support for multi-part archives : e.g. xxx.7z.001, xxx.7z.002, ... (see the context menu items ''Split File...'' to create them and ''Combine Files...'' to re-assemble an archive from a set of multi-part component files)
* Support for custom codec plugin DLL's.
The format's open architecture allows additional future compression methods to be added to the standard.
