UDF!!! Whats that?

[anispace]

When i inserted the Digit July05 CD i found tht it was in the UDF format.

isnt UDF supposed to be a format for DVDs and CDRs? So why is the Digit
CD based in the UDF format?Whats the advantage of UDF over CDFS??

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??
