Most of the time we come across files that are really hard to delete even if your try all sorts of permissions and overrides. Most common being that the file is under use by Windows error. LockHunter is another excilent tool to break your file free. Good thing its simple to use as it integrates straight into your system shell via right click menu. All you need is to highlight the file you want to remove and you can see what processes are using it after that you can either unlock it or kill the process or delete the selected file.

LockHunter is freeware, Windows only.
