Universal Disk Format (UDF) is a filesystem often used on DVD-ROMs (and other optical disc formats, such as Blu-ray Discs), but which is suitable for general purposes. Informally, it is the successor to ISO 9660. Discs containing both a UDF and ISO9660 filesystem are called a "UDF Bridge disc".
It uses little-endian byte order format, as people sometimes find out the hard way.

[edit] Software
Operating systems often include drivers for UDF. On Linux, a UDF image file can be mounted using a loopback driver (mount -r -t udf -o loop ...).
- isolyzer is a tool that verifies if the file size of an ISO image is consistent with the information in its filesystem-level headers. This can be useful for detecting incomplete (e.g. truncated) ISO images. Supported filesystems include UDF (as well as ISO 9660, HFS, HFS+, and hybrids of all of these filesystems).
