Is there a way to delete just one of my save files?

Hi @drummergirl231 Just popping a few links for you to manage your save files, and to help understand how they work..

If you're needing to work with Saved Games there's a good guide at Carls Sims 4 Guide also, you can go back to an earlier save if you need the "how-to" go to Carls Sims 4 Guide for directions on doing that and salvage from an earlier time before moving.

Hope this helps.
