.SID is Steam Game Data Backup File

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.

Audio file originally used by Commodore computer systems, but now more often used for playing the sounds on Commodore emulators and SID software players; often used for video game background music and can use mono or stereo audio formats; created for the MOS Technology 6502 processor, which can be emulated by newer desktop software to play the audio.

SID files may use the PSID format or the newer RSID (Real SID) format. While the PSID format is more compatible with general Commodore emulation software, the RSID format requires more complete emulation of the C64 hardware.
