1.  You don't want to use dump.  Dump will only dump full partitions.  It's
somewhat unlikely that you want the entire partition.  (I would be surprised
if you have permission to do so.) 


3.  You may prefer to use Zip, organize your stuff into chunks that zip into
sub floppy sized chunks, and keep it that way.  Would mean that you don't
have to spend forever inserting disks to get one file back.

4.  While there is some additional overhead for Next format vs Dos format, the
Next format is signficantly faster.  Many fewer yawns.
