On Windows, you cannot move or delete a file which is in use.
(Not "locked", but simply open by a process.)

This is a stupid Windows design problem, and Windows provides
a stupid non-solution for it in the form of a retarded API.

You have to use the Win32 API function MoveFileEx. MoveFileEx can be used to
move files not only immediately, but after a reboot (using the
MOVEFILE_DELAY_UNTIL_REBOOT flag). If you use this flag, and specify a null
pointer for the destintion name, then the file will be scheduled for deletion
at the next reboot.
