You've got to take ownership. Details depend on your OS, so I'm afraid I'll have to refer you google. For XP, google
XP TAKE OWNERSHIP.

my pc went through a F11 system recovery recently and I can open most of the folders and files but the music and photos that are in the "Owner's Documents" give me a "Access denied " error. I tried changing the system permissions and nothing, file recovery or extraction programs don't work because the files are not deleted or lost. How do I bypass the error or get the files?
