A couple of freeware UDF apps that I'd recommend adding to your
toolbox:
ISOBuster [freeware/shareware -- sw vers has added functionality].
ISOBuster is the best recovery software I've ever used for
UDF-formatted CD's/DVD's. It's quite fast, and does an excellent job.
Also filenames are restored in much larger percentage than with other
similar apps, in my experience. Whatever UDF prog you use, you really
need a copy of this, as UDF formats can be quite unstable and it's not
like you can simply share CD's with others via typical CD formatting,
since by definition UDF is unique. Now, you can install readers, InCD
or DirectCD, or sw apps like Jet Storage UDF. You will need such apps
to read UDF discs. [And also, InCD and DirectCD are incompatible, so
you can't have both installed/in use at the same time. As I recall,
Nero makes a little freeware app to temporarily disable DirectCD if it
finds it on your system - don't know if reverse is true with DirectCD.]
Anyway, ISOBuster is designed as a data recovery tool, so I don't
recommend it just to copy data off a perfectly good UDF-formatted disk
just to use the files. It's just another excellent recovery tool when
your UDF software fails [and believe me, it will].

For UDF formatting/burning, an excellent freeware app is "Easy
Burning." It's a great CD-DVD burner that adds UDF.

While you're there, you may find several other excellent freeware
CD-DVD burning tools.
Shareware-wise, the above-mentioned Jet Storage UDF is supposedly one
of the best UDF burners, though I haven't tried it. It does NOT run
under Win98SE & before.
