SIM File Extension

Steam Game Backup Information File – file format by Valve

SIM is a file extension for a Steam Game Backup Information File, developed by Valve. These files contain information about a game and its associated files, which are used by Steam to create backups of installed games.

What is a SIM file?

A SIM file is a Steam Game Backup Information File that contains information about a game installed on a computer. This information can be used to reinstall the game at a later time, either on the same computer or on a different one. It is important to note that SIM files cannot be used to install games that are not already owned.

How do SIM files work?

When a game is installed on a computer, Steam creates a SIM file. The file contains information about the game, such as:

  • The game’s title.
  • The game’s release date.
  • The game’s size.
  • A list of the game’s files.
  • Information about the game’s dependencies.

When a user wants to reinstall a game, they can select the “Install game” option from the game’s menu in Steam. If the user has a SIM file for the game, Steam will use the file to reinstall the game. This can save the user a lot of time, as they do not have to download the game files again.

Steam Game Backup Information File (.SIM)

The Steam Game Backup Information File, denoted by the .SIM file extension, is an essential component of Steam’s backup system. It serves as a metadata repository, providing detailed information about installed Steam games. When users back up their games, the .SIM file captures crucial details, such as game title, installation path, and associated Steam ID. This enables easy restoration of games by simply transferring the .SIM file and the game files themselves, ensuring a seamless recovery process without the need to reinstall.

Furthermore, the .SIM file plays a significant role in maintaining the integrity of backed-up games. By storing information about game updates, DLCs, and other modifications, the file ensures that the restored game accurately reflects the player’s progress and customizations. This eliminates the need for manual configuration or potential data loss during the restoration process. Additionally, the .SIM file facilitates the transfer of games between different computers or storage devices, making it a versatile and convenient solution for managing large game libraries and preserving important gaming experiences.
