Re: sims 4 files
@astridou4 I've moved your post to the Sims 4 PC tech section.
Is Sims 4 reading data from OneDrive, or is that where your saves are? If it's the latter, you can copy your saves to your desktop, disable OneDrive's automatic syncing of Documents, and move the saves to Documents\Electronic Arts\The Sims 4\saves. You can do the same with the contents of Tray as well as any other user data you want to keep.
If this isn't what's happening, please post the full file path to the saves you see. You can write [username] instead of your username if you want, but leave the rest of the file path intact.
