Re: Sims 4 with my save data won't open

i'm not exactly sure what you mean by "over save version", and they aren't corrupted.

@41111037  don't move the entire folder back into documents only move over your save games because outdated mods can cause game issues like example not starting up

I have the same issue and not sure how to resolve it based on the replies listed above. I think i am currently having issues with onedrive and desktop locations. when you say move save files to electronic arts folder, which ones ? there are heaps within the sims 4 folder e.g scratch, chache, chachestr,configreovveride and more

@buddabah  When I said save files, I meant the files that store actual save data.  These are labeled Slot_[number].save and are found in Documents\Electronic Arts\The Sims 4\saves.  If you remove your existing Sims 4 folder and let the game create a new one, you can copy the files from the saves subfolder inside the old Sims 4 folder into the saves subfolder inside the new Sims 4 folder.

Most of the other files in the Sims 4 folder are expendable and will regenerate as needed.  The only exceptions are Tray, which contains your saved households and builds; Mods, which holds mods and custom content if you use either; and Screenshots, which contains screenshots.  You can ignore the rest, and in fact it's a good idea to do so in case one of those files has become corrupted—leaving it behind means getting rid of that corruption.

If you're not sure what's going on with your folders, feel free to post a screenshot or two; include the address bar above the list of files and folders.
