Have you ever run into a situation where you wanted to delete a file,
but Windows simply wouldn?t allow you to do it? Personally, these
things happen to me all the time, especially when I?m at a client?s
house trying to get their machine clean of malware. Have you ever
tried deleting a locked file using common windows commands? If so,
then you?ll know that this is just not possible.
if yes, you can try special tool Long Path Tool
