I try to delet some files on WinXP Pro and then i get the "make sure the disk is not full or write-protected and that the file is not currently in use" error.
I try to uncheck 'read-only' but it says the same error, I try SHIFT+DELETE method, and safe-mode, and killbox, and some other methods.
I have taken control of that folder.
