What is a SIMS3.BACKUP file?
Backup file created by The Sims 3, a life simulation game that gives you control over simulated persons, or "Sims," and how they interact with their world; contains saved game data up until the most recent save, which is contained in the .SIMS3 file; includes game progress like new vehicles, buildings, and characters; located in the "Saves" folder of the The Sims 3 directory along with the SIMS3 file.
If you have a corrupt SIMS3 file that does not load, you can restore the game from your SIMS3.BACKUP file.
- Copy the SIMS3 and SIMS3.BACKUP files and paste them into another folder for backup purposes just in case you make an error.
- Go back to your "Saves" folder and delete the SIMS3 file that is not loading and delete it.
- Remove the ".BACKUP" from your SIMS3.BACKUP file so that it looks exactly like the corrupt SIMS3 file you just deleted.
- You are now able to load your game from the game menu.
