@Phil25:
Which files did you get from the Unlha (or Unlzx, about the same difference)?
If you got a .adf file then, again, Aminet can help with a piece of software called adf2disk. With that you can, from the CLI, write the ADF file directly to floppydisk.
If you got a .dms file then Aminet should be helpfull as well (actually, it's always helpfull) in providing software to write the DMS to disk.
