There probably is a way, although I've never found it, despite having
played with the setting under Adaptec's Easy CD creator. What I do is
tar all the files up into one big tar file, then write that to CD. It
means I have to untar them to read them, but that is no real problem.

A basic ISO-9660 filesystem cannot handle long filenames itself. You
normally use RockRidge extensions to support long filenames on Unix
systems. (Microsoft uses its own Joliet extensions for similar
purposes.) I'm not familiar with the Windows software you mention, but
if you can turn on RockRidge extensions, do so. There's no reason why
you can't use both RockRidge and Joliet extensions on the same disk,
AFAIK.

Yup, another case of MS ignoring readily-available standards and coming
up with their own.

Windows uses "Joliet" for long filenames, whilst Solaris (and most of the
rest of the world) use "Rockridge". By default most windows software will
burn with Joliet only, whilst most Unix software will do RR only by default.

Enable both Joliet and Rockridge on the CD when making the ISO. The two
can co-exist, and then each OS will read whichever extention is requires to
get the long filenames.

Alot of windowssoftware for creating CD's are broken in this respect,
at least it was.. I have seen at least two different windowsprograms that
either created defective RR-discs, or claimed that "8+3 filenames is
maximum with rockridge"..

But with a working CD-creation software it should be fine with RR if
your files "fit into" the limitations of rockridge..

I've managed to get Rock Ridge burned on windows (see below), but I
typically did the same thing - just put things in tar files and burned
them using iso9660 format. In case you want to try Rock Ridge or a
combined Rock Ridge/Joliet, here are a few pointers that may help
(YMMV of course)

- Try the windows port of mkisofs - it may seem a bit clunky, but it
works fine. Find it at
http://www.rodsbooks.com/rhjol/mkisofs-win32.zip . Actually I found it
on the parent page http://www.rodsbooks.com/rhjol/rhjol-cd.html ,
which has helpful info (just to give credit where it's due).

- Check out the CDR-FAQ at http://www.cdrfaq.org. In particular,
http://www.cdrfaq.org/faq06.html lists about (conservatively) 8
billion different CD burning packages for windows. Who knew? Anyway,
at least a dozen of them claim support for both Joliet and Rock Ridge
(among others) - I haven't tried any, but some might even work.

Hope this helps,
