What is a .CSM file?

The file extension .CSM stands for Character Studio Marker File. It is a type of backup file used by Steam, which is a platform that allows users to download, play, and manage games and other software. The .CSM file contains backup data for games that are played using Steam. This file is similar to other file types such as .CSD and .SIS, which are also used for backing up game data in Steam.

To open a .CSM file, you need to use the Valve Steam program. Steam provides a feature to manage these backup files. If you need to restore a game from a .CSM backup file, you can do so by opening Steam, then going to the "Backup and Restore Games" option. From there, you can select the .CSM file you want to restore. Typically, the .CSM file, along with its related .CSD and .SIS files, is stored in a specific game folder within the "Steam Backups" directory on your computer.

This setup helps in keeping your game data safe, and allows you to restore the game to a previous state if needed, using the backup files stored in these formats.
