My files are deleting themselves when i play

The problem is that you are using One Drive. I used to use it for backups which for the Sims 4 took forever and the program did delete files without my permission. It was impossible to completely get rid of it so what I do now is to block it. It tries to come back every time I have to reboot so I make sure to turn it off if I have to restart my computer. This does not remove any of the other files on Word that are saved as backups to One Drive. I recommend you turn One Drive off.  I also changed my save file to a different location and combed through One Drive to get rid of any files it was backing up for my Sim games.

One Drive is nasty for any games that you play infrequently. It deleted some game files from my Steam game saves and I cannot recover them because I always said yes to file deletions.

Sorry for the delayed answer

Thanks so much for the help, I ended up deactivating one drive every time i turn on my computer so that it doesn't happen again.

Sorry for the delayed answer.

I ended up doing just that and it doesn't happen anymore.

Kiana171  If your user folder isn't inside OneDrive, you shouldn't need to deactivate OneDrive every time.  Or you could unlink your PC from OneDrive entirely.  Without a link, it can't touch your data.

Let me know if you need further help.
