I found it in the readme.txt inside the .zip. I can mail it
to you this evening from home, but the file is kinda old now.
I would PRESUME, that all newer versions of CDFS.IFS
support Joliet (one "t").

visit: http://www.roxio.com/en/support/cdr/filesystems.html

for a nice table and some explanations of what can be read and displayed
by which other OSes -- alas, no OS/2 references. ROXIO is the (new) name
of the folks that make/made Adaptec Easy CD Creator, the most popular
Windows CD burning software.

I was incorrect. disregard my wild guess. See below.

Upon reconsideration, _and_ studying the above-referenced table, it seems
that, under Joliet, the associated DOS-standard name for each file is also
recorded on the CD. So perhaps OS/2 is reading ONLY that name. It cannot
hurt to try Steven's "/w" suggestion.

Visit: http://www.warpupdates.mynetcologne.de/english/hard_cddvd.html

for a brief mention of the /w switch, and
a pointer to SW Choice for the UDF File System (subscription) files at:

http://service.software.ibm.com/os2dd/swc/udf.exe

The IBM UDF driver, which I've not used, may permit reading the long
filenames. v1.50 was released in July.

For maximum compatibility, it appears one should limit CD filenames to 30
or 31 characters, instead of the 64 characters Joliet permits.
