A 7z file is also known as a 7-Zip compressed file and was developed by Igor Pavlov. It was developed in the late 1990s before being finally released in 1999 and is a compressed archive which uses 7 different types of open source archive technology including LZMA compression which compresses at an estimated 1MB/s and decompresses at up to 20MB/s. 7z files are particularly popular because of how efficient they are. They can contain multiple directories, as well as files, all of which are compressed which means that they support files up to the size of 16,000 Petabytes. To open a 7z file users can use 7-Zip, WinZip for both Windows and MacOS and File Viewer Plus.
