Attached Link: Freefile

I wouldn't claim to understand what's going on but as I glanced through this I wondered if a little utility that I remembered downloading some months ago would actually help you in your situation.  I've never had cause to use it yet, just downloaded it for the time when I expected I'd get one of those 'access denied' messages again which do crop up from time to time.

This may help you at least find what is blocking your access

I'll copy the blurb in here too so you can tell without having to open the page

"Cannot delete file: Access is denied - "Make sure the disk is not full or write-protected and that the file is not currently in use." "There has been a sharing violation." "The source or destination file may be in use." "The file is in use by another program or user." - These are typical error messages you get when you try to delete a file that is locked by a process. But which process has locked the file? Use FreeFile to automatically find out which process is locking your file, and free the file by ending the process.  Free download from Shareware Connection - FreeFile will free a file by finding the process that holds the lock, and allow you to terminate it.
