Tray and save files

Hi ndnvtd8at77z 

The tray files contain all the Sims and houses you saved to your library. Saves contains your save game.

Both are important.

Thank you for letting me know! I have another question and I'd really appreciate if you have an answer. If I go to my sims document folder, and I go to saves, I see "save" and then versions, what are those? Can I delete the versions

The .save file of a certain slot is always the newest version, the save.ver files of the same slot are older versions. The .ver files can be used to restore a save if something is wrong with the .save. file.
