Re: Cannot delete save files
@JasonVega2 If you hover over the folder icon with your other save data, you'll see the file name for a given save. You can write down that file name and then delete the corresponding file from Documents\Electronic Arts\The Sims 4\saves. You can also sort this saves folder by modified date if you're looking to delete a number of old saves at once.
I agree that this isn't ideal, but you can make it work with some extra effort.
