Download 7-Zip File Archiver Software For Windows Free

Download 7-zip for windows open-source and free file archiver program that works on multiple platforms, a utility used to place groups of files within compressed containers known as “archives”. 7-Zip uses its own 7z archive format but can read and write several other archive formats. It is developed by Igor Pavlov and was first released in 1999.

The file archiver software can be used from a command-line interface as the command p7zip, or through a graphical user interface that also features shell integration. Most of the 7-Zip source code is under the GNU LGPL license; the unRAR code, however, is under the GNU LGPL with an “unRAR restriction”, which states that developers are not permitted to use the code to reverse-engineer the RAR compression algorithm.
