OneDrive is one of the most infuriating backup programs ever. It will eat up all your space on your c drive and if you want to stop it, you had better have some vacation time coming up because it's a job and a half. Erase them from the drive and it's immediately repopulated by the cloud. Want to delete them from the cloud so that doesn't happen? Lol good luck. When you finally do get it figured out and solve the problem... It just gets reinstalled on the next update! Yay!
