No, before we get too far off the track...

Rockridge is a purely logical extension of ISO 9660.  Rockridge uses a
reserved file name in each directory, something like _YMTRANS.TBL, which is
simply a list of the long file names which are to be associated with the
short file names encoded by ISO 9660.  A Rockridge-aware systems uses that
list to make the long file names appear as the file names, completely
hiding the native ISO 9660 file names.  Basically, Rockridge provides
UNIX-ish extensions to the ISO 9660 file naming conventions, and not much
else: long file names, case sensitive file names, and soft links.

If you look at a Rockridge disk using a pure ISO 9660 reader, such as
MSCDEX, the whole structure will become immediately obvious.
