Wow! what a mess. Have you tried Unlocker 1.8.7
http://www.softpedia.com/get/System/System-Miscellaneous/Unlocker.shtml
Helps delete locked files with error messages like:
· Cannot delete file: Access is denied
· 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.
· Make sure the disk is not full or write-protected and that the file is not currently
in use.
Good luck.
