  I believe that if you write to a CD-R in multiple sessions, if a
later session includes a file that has the same path/filename as a
file from an earlier session, the earlier file becomes inaccessable
(except to specialized tools).  This sounds like the effect that you
want.

  There is a downside:  You cannot write additional sessions to the
disk once you "close" it.  That could be a problem, because some
older CD drives have trouble reading a CD that has not been "closed".
 [I think you can get away with not supporting *very old* drives that
can't handle multi-session disks....]
