Checkpoint64 automatically backs up your game saves and keeps every version, so a corrupted, overwritten, or mod-broken save is one click from being restored. It ships with presets for 75+ games and 7 emulators, so it already knows where each save folder lives.
Below are the in-depth guides — where the saves are stored, how they break, and how to roll them back. Just need the folder path? The A–Z list of save file locations covers every supported game, per platform.
Don't see your game? If it writes its save to a folder on disk, Checkpoint64 can back it up; point it at the folder and go.
