I recently had to re-install Windows Vista, and I have a problem I didn't have before. I want to move a folder and files, from my c: drive to an external drive. I get the message that I don't have permission, and to try again. This doesn't do anything. I can't understand this, as I am the only user, so should have full permissions. One thing I did notice, is that the files are read only, but changing the attributes doesn't help.
