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, but can read and write several others.
A self-extracting archive created using 7-Zip. A self-extracting archive (SFX or SEA) is a computer executable program which combines compressed data in an archive file with machine-executable code to extract the information. Running on a compatible operating system, it does not need a suitable extractor in the target computer to extract the data.
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 24.08. [2] The 7z file format specification is ...
Other well-known software with CAB archive support includes WinZip, WinRAR or 7-Zip. The aforementioned cabextract is a common tool for Linux systems, [13] but is only capable of extracting archives. The gcab tool however can both extract and create CAB archives. [14] For a full list, see Comparison of file archivers § archive formats.
libzip is an open-source library for handling zip archives. It is written in portable C and can thus be used on multiple operating systems. It is based on zlib. It is used by PHP's zip extension for zip file support [2] and MySQL Workbench. [3] It is also used by KDE's ark archiving tool for zip archive support.
ZIP files generally use the file extensions.zip or .ZIP and the MIME media type application/zip. [1] ZIP is used as a base file format by many programs, usually under a different name. When navigating a file system via a user interface, graphical icons representing ZIP files often appear as a document or other object prominently featuring a zipper.

The 7-Zip implementation uses several variants of hash chains, binary trees and Patricia trees as the basis for its dictionary search algorithm. In addition to LZMA, the SDK and 7-Zip also implements multiple preprocessing filters intended to improve compression, ranging from simple delta encoding (for images) and BCJ for executable code. It ...
