I am using Windows XP Home Edition. When I try to delete a folder I have named cygwin. When I try to delete it or any file or folder within it, there is a long pause, and then an error pops up, saying:

Cannot delete Cygwin: Access is denied. Make sure the disk is not full or read-write protected and that the file is not currently in use.

I have tried deleting the folder and the files it contains with FileAssassin, and unlocking it with LockHunter. Neither report any errors unless I try to have them delete the file or folder, then I get an error message saying Access Denied. I have rebooted into Safe Mode to change the ownership, but I get Access Denied when I click OK or Apply. How can I delete this folder?
