Introduction to 7-Zip

7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. 7-Zip uses its own 7z archive format, but it can read and write several other archive formats.

The program can be used from a command-line interface as the command p7zip, or through a graphical user interface that also features shell integration. 7-Zip is available for Windows, Linux, and macOS. It has been praised for its high compression ratio and speed.
