If your data is corrupted or you simply want to revert to a prior save, The Sims 4 automatically stores numerous save points for you to choose from.
Your save files can be found in the following location:
Documents > Electronic Arts > Sims 4 > Saves
Within that folder, you will see a long list of files with names like Slot_000000012.save or Slot_000000012.save.ver1. You will notice that each file number has up to six versions. The one with the .save file extension is the primary version of that save point–the one that would load if you launched the game and continued from where you left off (or used Load Game in the main menu to choose an older save point). The other instances of the file represent older points within that saved game, where the game automatically preserved your progress incrementally. The higher the version number, the older the file (.ver4 is the oldest save point within the series).
If you find that your game is corrupted as of the latest load, you can easily revert to any older version of that same save point, potentially losing no more than a few Sim hours of progress. Start by identifying the save point you want to use:
- Is it definitely the latest game you’ve been playing, or do you want to go back by a few days?If your folder view is set to show details, you will see your files displayed with date and time information, making it easy to choose the newest set of save points.
- If you want to go back further in an older save, you can match it to your save points in-game via the Load Game menu.The in-game save points show date and time information, so you can match them against the set of files in your Saves folder.
Important: After you have matched your save points in-game to your set of save files, be sure to close the game. Never alter game files while the game is running.
Once you have chosen the save point you want to return to, select the primary version of it (the one with the .save file extension) and move it to another folder location for safe-keeping (you could instead choose to rename or delete it if you prefer). Now you will have a set of files that all have the file extensions marking them as older versions of that save point. You can choose any one of those to make primary, depending how far back you want to go.
- To revert the smallest amount of time and progress, choose the file with .save.ver0.
- To revert the most time and progress within this save, choose the file with .save.ver4.
In order to make the file you choose become the new primary save point, simply right-click the file and choose Rename. Delete the part of the file name after .save and hit Enter.
Example: Slot_000000012.save.ver4 should now be Slot_000000012.save
Now, launch The Sims 4, and choose Load Game. Select the save point you want to open, and the game will load the file you renamed as the primary for that save point.
