One objective of UDF is to replace the ISO9660 file system on optical media (CDs, DVDs, etc).

Universal Disk Format (UDF) is a file system specification defined by OSTA. UDF is required for DVD-ROMs, and is used by DVD to contain MPEG audio/video streams.

Universal Disk Format (UDF) is a CD-ROM and DVD file system standard developed as a means of ensuring consistency among data written to various optical media, by facilitating both data interchange and the implementation of the ISO/IEC 13346 standard. Instead, even though the program that does the burning will do so using the UDF standard, it most likely associates the file with itself by appending a different file extension to the end of the file name. UDF is a common file system used by optical media burning programs to store files on discs, so the actual UDF file extension (.UDF) might not be as prevalent. In practice, it has been most widely used for DVDs and newer optical disc formats, supplanting ISO 9660. Universal Disk Format (UDF) is a profile of the specification known as ISO/IEC 13346 and ECMA-167 and is an open vendor-neutral file system for computer data storage for a broad range of media.
