Software Overview

Main Features

7-Zip is a free, open source application used to archive and compress data. It can combine a number of files into one archive or simply reduce the size of a single file for quick transfer.

7-Zip uses the 7z (.7Z) archive format by default, which provides a higher compression ratio than the .ZIP format. Along with 7z, 7-Zip supports ZIP, WIM, RAR, GZIP, BZIP2, and XZ compression formats. It also supports a multitude of package formats, such as TAR, MSI, DEB, ISO, CAB, RPM, NTFS, and Z. Along with packing and unpacking capabilities, 7-Zip is a useful file manager that allows you to copy and move your files to other locations.

7-Zip is a durable archiver and compression application. It supports many packing and unpacking formats and doubles as a useful file manager. While the 7-Zip interface is simplistic, it is a powerful, lightweight file compression utility.
