This is not correct. The initial ISO9660 standard did specify the 8.3 format but there are now extensions that do what you describe. Recent versions of "mkisofs" support RockRidge (long filename under UNIX support) and Joliet (MS long filename support) so you are not restricted to the 8.3 format. I wrote a couple of CDs the other day under FreeBSD (3.4-STABLE) using "mkisofs" with RockRidge support and the long filenames work fine. As this was data from a UNIX system I wasn't concerned with Windows support. > Next question. Under Windows, there was a program called Adaptec >Direct CD that pretty much allowed you to treat a CD-RW disc as "a really >big floppy disk" (I think that was from the docs).

The is called "packet writing" and the drive has to support it as well as software. I haven't seen any Unix tools to date (although I haven't done a comprehensive search) that supports this. Shaun.
