7-Zip 18.05 – Final Free Download

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.

7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license.

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.
