  Rock Ridge ISO 9660 CD extensions? 
 The Question is:
 
Do you know what Rock Ridge is?
 
If I make an ISO9660 CD, by definition, it has file names in the 8.3 style
(e.g. ABCDEFGH.IJK).
 
If I mount such a CD on VMS, I see directories and files which abide by the
8.3 standard.  This is good.
 
If I mount such a CD on some UNIX boxes, I see directories and files which
abide by this 8.3 standard.  Often, I can throw an option switch which tells
UNIX to use "Rock Ridge" extensions in dealing with the 9660 CD.  That means
that the normal 8.3 9660 f
iles are mapped to longer and more stylish
UNIX file names.  From the UNIX user's point of view, the 8.3 filenames do
not exist - he only sees the longer names.  This is better.
 
I need to be able to use such CDs along with the longer file names on VMS.
 
I can imagine a simple program which reads the 9660 directory and simply
makes a mapping between 9660 8.3 filename and the longer RR filename.  Then
I could make a .COM on VMS to copy the 8.3 files from CD to their more
elaborate filenames on disk.
 
Does such a thing exist?

 The Answer is:
 
  The OpenVMS ISO 9660 CD-ROM file system does not support the Rock Ridge
  CD media extensions.
