Re: Is there a way to delete just one of my save files?
@drummergirl231 I've moved your post to the Sims 4 general discussion section.
Each separate save, as viewed in the Load Game interface, has its own slot. The oldest save is Slot_00000002.save, and the game counts up from there. Additionally, the last five versions of a given save before the most recent one are also preserved; those are the files labeled Slot....save.verx, with .ver0 being the most recent and .ver4 the oldest. When you load a save, play for a while, and then save your progress, the save version you loaded is demoted from ...save to ...save.ver0, .ver0 is demoted to .ver1, etc.
What it sounds like is that when you last played this save, you only saved your progress twice, so there are only two files from August 6. The earlier versions are still from the same save, they're just dated when they were created, not when you last played. But since all files labeled (in this case) Slot_00000003.save (with or without a .verx) correspond to different versions of the same save, you can remove all the files labeled Slot_00000003 and leave the rest.
If you want to be totally sure you have the correct files, you can move them to the desktop or elsewhere first, then load your game and see what's been removed. If you accidentally grabbed the wrong save, put the files you moved back into the saves folder and remove something else, then load the game again and check your work. As long as nothing gets deleted, it can always be restored later.
For future reference, you can also back up the entire saves folder (in cloud storage or on an external hard drive or USB), in case you need it later. So if for example your hard drive fails or something else happens to your data, you're never in danger of losing all your saves
