The cabinet file format, shortened CAB, is an archive file format that was developed for the Microsoft Windows operating system. The format supports the lossless family of data compression algorithms as well as embedded digital certificates that facilitate data integrity. Archives created using the CAB format have the filename extension .cab and are recognized by the operating system through the identifying 4 bytes in the header. CAB enjoys support by other Microsoft technologies such as the Setup APIs, Windows Installer and others. In fact, some earlier integrated development environments developed by Microsoft could create setup files that were organized as CAB files.
