I would like to understand and be able to teach my students a summary of all file DVD/CD systems.
I am a bit confused about Joliet, ISO, /R, /RW, DVD+/-, DVD-RAM, session, UDF, CD-Direct etc.
For example I have two XP Pc's one can update the same CD/RW the other cannot.
The ideal would be a tree structure like a CD can be x or Y file system, x can be a or b or c etc.
Does that exist ?
