                                (0 specifies the current partition,

                wipe \\.\PhysicalDrive1
                wipe \\.\D:
                wipe C:\mypath\*.exe
                wipe c:\mypath\afile.*
                wipe -p 1 \\.\Tape0
                wipe \\.\Tape0  (wipes current tape partition)

        Notes: Tapes are wiped by sending the tape drive a command to erase
        the volume unless the tape drive does not support this command.  If
        the drive does not\nsupport this command,  wipe will attempt to erase
        the volume in the same manner as for disk files.

        Use wildcards ('*', '?') to indicate multiple files to wipe.
