   some tool/utility only has dos version. if you want to input/output
something to dos, then samba is the best partner. you won't want
usb-disk or floopy under dos. BTW, dos has universal storage and
network drivers,although it will become broken by future uefi-only
computers.

   I have test "DOMSAM\fred" and it can not work. so maybe  it is the
bug of samba 4.7?
