Hello, I recently had a problem on my computer that I was not sure how it's handled. When my computer crashed asking that the disks are full, I deleted large files to see what the problem was coming from. When I restarted my computer, my computer had a automatic update and changed everything on my desktop. My screen's background disappeared, my files were hidden, and my computer still says the same problem. Everything installed is still there, but I cannot access the files of the program. What's going on?
