I see that Nero has the option of creating a UDF CD and a UDF/ISO CD. I created a UDF/ISO CD and all that I could find different from the standard Data CD was that it could hold aproximately 15MB less than a standard data CD. The usual file name and directory restrictions still apply. Also, Windows reports the CD as having UDF file system instead of CD-FS, but I could see no other difference.
Would anyone know if there is any advantage of creating a UDF CD over a standard ISO CD, e.g. speed or performance difference? This is different from the UDF CDs that Direct CD create as once Nero has finished burning the CD, I cannot add more files unless I add another Multisession to the CD. I.e. just like a standard data CD.
