Files may be used by some process thus impossible to delete. If you have open other files on mentioned USB drive, close them before deleting. Also some shell extensions may not close files directly after file property retrieving. Try to unmount/eject and replug mentioned USB drive before file manipulation. If system warn you that drive is still used, reboot the system.
