7-Zip 26.00 – Free File Archiver

7-Zip is an open source file archiver with the high compression ratio predominantly for the Microsoft Windows operating system.

It operates either as a command line program or with a graphical user interface. It also features integration with the Windows shell environment.

Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And it compresses to zip format 2-10% better than most of other zip compatible programs.

7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license. This file archiver works on all Windows operating systems, from Windows NT to 10 (32-bit and 64-bit).
