i believe u r correct. really wanna find out since it wont let u in is delete all but the most recent restore point in disk clean up and see what the size of the folder is afterwards. that is alot of restore points to be using up 3.5 gigs and my restores fail neways when i try to go back to more than a week or 2 prior. so i would reclaim ur disc space to use for better things than holding useless old restore points.
