Universal Disk Format


(n.) Abbreviated as UDF, a 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.

UDF, defined by the Optical Technology Storage Association (OTSA), is a subset of ISO 13346, an interchange standard for non-sequential recording of data.
