When the actually file or directory the path refers to does not exist.

No.  The File and Dir objects can be created without opening files or
creating directories.  This is different than Python.  For a File you leave
the mode string empty to mean create the object without opening the file.
The Dir constructor never creates a directory.  You have to use Dir.make()
to create a directory.

    # make sure directory exists before using
     if not dir.exists?():
          dir.make()

This was just a practical decision.  I could be talked into making it
recursive.  My thinking was that you could add code to make it recursive
yourself.
