if you mean DirectCD and InCD, yes its UDF. There might be support for
writing MSDOS filingsystems on CD-RW, but i've never seen it. On a CD-MRW
it could technically be possible to even put FFS on it though our code
doesn't allow it.
DirectCD (they market it under Drag2Disc now IMDR) can also create a
ISO9660 filingsystem as a piggyback on UDF.
Support for reading and writing UDF is currently in my
pkgsrc/misc/udfclient package and full fledged kernel read and write
support is a work in progress; can't give a deadline though vfsops didn't
take apalling long to develop, its not writing yet and the vnops are not
even started on.
Cheers,
Reinoud
