Last night I backed up on a USB drive all my animation programs and a huge game that I bought on Steam because it was borking up my computer really bad. So I started it backing up around 11:00 PM, and I let it back up all night. I woke up this morning to see that it hadn't backed any of my programs onto the drive but instead, made a duplicate of them all in one zip folder and now I have no idea where they could be. I was successfully able to back them up today but the duplicate is no where to be found but I know it's still on my computer because I have 745 GB left of a 1TB of storage, when originally when I woke up this morning, I was shocked to see I had lost 100 more GB then what I had last night, going from 759 GB to 669 GB. If that duplicate hadn't been made, I would be in the 880's somewhere in GB's of storage. Any tips or information on how to solve this problem would be greatly appreciated! Thanks!
