7-Zip File Archiver

October 11, 2019 - (Freeware)

7Zip Filehippo is an open-source and free file archiver Software, a utility feature used to place groups of files within a compressed folder known as “archives”. It is developed by Igor Pavlov and was first released in 1999. It uses its own 7z archive format but can read and write several other archive formats. The program can be used from a command-line interface as the command p7zipor 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.

You can use 7-Zip on any computer, including a computer in a commercial and business organization. You don’t need to register or pay for it. It also creates password-protected file zip files, as well as self-extracting zip files. Most of the code is under the GNU LGPL license. Some parts of the code are under the BSD 3-clause License. Also, there is an unRAR license restriction for some parts of the code.

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 7-Zip compresses to zip format 2-10% better than most of the other zip compatible programs. This is an ultimate free zip folder for sure.
