What is .SID file extension?

Backup file created by Steam, an application used to download and manage Valve video games on desktop computers; contains compressed game data created by the Steam backup feature (steambackup.exe program); used to backup games to DVDs or other external media. SID files are created with a .SIS file and a .SIM file, which provide metadata necessary to restore backup game data. SID files use the naming convention {game}_disk{X}_{Y}.sid, where "game" is the name of the backup game, "X" is the disk number, and "Y" is the backup file number on the disk. NOTE: Steam backups do not include saved games, custom multiplayer maps, or configuration files. You must backup and restore those files manually.
