Hi
 The Polymorphics DOS uses   <disk>dirname>filename.ext  or
  <disk>dirname>subdir>filename.ext .
 It is funny in that the file names and directory names can
be up to 32 characters but the extention is only 2 characters.
If using the disk name, it can only be 8 characters.
They also had subdirectories from the start. This DOS is like
most of the older ones in that it one had to PACK every now
and then to recover deleted disk space. Since it was created
before DOS, I wonder where it got its roots?
