Re: My whole sims 4 mod folder and user data got deleted windows 10 HELP
@whatsurdesti Generally speaking, if your files have been deleted and the recycle bin emptied, there's no way to get them back. Even file recovery services usually don't recover enough data to restore a Sims 4 save to working order, so that would be a waste of money.
I'm not sure what the error about your drive not being installed is about, but if you do sometimes use an external storage device (hard drive, USB stick, whatever), is it possible you copied some Sims 4 data to that device at some point? If so, just plug it back in and take a look.
Otherwise, check OneDrive to see whether any Sims 4 data landed there. If it did, you can download the files to your computer, and they should work.
In either case, the game will read the files once they're back in Documents > Electronic Arts > The Sims 4.
