UDF-Universal Disk Format
This is universal vendor-independent file system for optical media designed for data interchange and portability, allowing an operating system to read, write and modify data stored on optical media that was created by another operating system.
DVDs are based on the UDF format and CD-R and CD-RW disks use UDF as an optional second standard.
I don't know why this has been used for CD's...Are u sure it has been used??
