File created in the Universal Disk Format (UDF), a disc imaging format used for storing files on optical media; stores a collection of files using the directory structure specified in the UDF standard; can be used for burning DVDs, CDs, and other optical media; allows files to be deleted and modified on the target disc even after they have been written.
The UDF standard is developed and maintained by the Optical Storage Technology Association (OSTA).
