ladykyera999 The files that end in .bad are not usable—the game renamed them specifically because the saving process corrupted the data enough to be obvious. But it looks like the backup might still be intact.
Delete the saves that end in .bad, since they're not recoverable. Then delete the .backup from the other save, so the folder is just labeled Hammer.sims3 , and it should be available to load at the Main Menu.
Before you actually try to play it though, I would strongly suggest making a copy of this backup. When a save goes bad, sometimes it's random, but more often, that means it's been getting increasingly corrupt and may break again soon. So if you run into the same issue before too long, you'll still have this intact backup to revert to.
On the subject of save corruption, let me know if you'd like to talk about how to try to prevent it, which basically means adding some mods to do most of the work for you.
Separately, I can see that OneDrive is syncing your files. If you don't want this to happen, I have a guide to getting rid of OneDrive the proper way and without losing any data.
