What is 7-Zip?

7-Zip is an open source file archiver. 7-Zip operates with the 7z archive format, but can read and write several other archive formats. The program can be used from a command line interface, graphical user interface, or with a window-based shell integration. By default, 7-Zip creates 7z format archives with a .7z file extension.

About  (from Igor Pavlov)

7-Zip is open source software. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license: GNU LGPL + unRAR restrictions. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.


The most used version is, with over 98% of all installations currently using this version. Upon installation, it defines an auto-start registry entry which allows the program run on each boot for the user which installed it. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. When installed, it will add a context menu handler to the Windows shell in order to provide quick access to the program. The main program executable is 7-zip.dll. The software installer includes 10 files and is usually about 1.07 MB (1,122,816 bytes).
7-Zip has been seen bundling various 3rd party software during the installation process. Make sure to check for and remove unused programs.
