Disk image extractors

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 has its own archive format called 7z introduced in 2001, but can read and write several others.

WinRAR is a trialware file archiver and compression utility for Microsoft Windows, developed by Eugene Roshal of win.rar GmbH (RARLAB) since 1995. It can create and view archives in RAR (a format created by Roshal) or ZIP file formats, and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC-32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives.
