I am using the Home premium edition of Vista. My computer crashed twice last fall and I had to reinstall everything. Both times it crashed a backup folder was created in my C drive. The backup folders appear to contain complete copies of everything that was on my computer C drive at the time of the crash. The problem is that both folders require about 23 GB of memory and between them they are consuming more than half of my hard drive, which is now almost full. I cannot delete the backup folders. Even though I have full control I keep getting a message saying "Destination Folder Access Denied." I have tried changing the folder's permission settings but nothing works. Any suggestions?
