This request command returns the CRC-32-IEEE of the specified Z88 file. The information returned is a hexadecimal string of 8 nibbles representing the 32bit value (common standard, as seen in ZIP files).

If the specified file cannot be found in the Z88 filing system (RAM or File Cards), only ESC "Z" is returned.
