Universal Disk Format (UDF) filesystem

Updated: April 19, 2023

The Universal Disk Format (UDF) filesystem provides access to recordable media, such as CD, CD-R, CD-RW, and DVD. It's used for DVD video, but can also be used for backups to CD, and so on.

The UDF filesystem is supported by the fs-udf.so shared object. The devb-* drivers automatically load fs-udf.so when mounting a UDF filesystem.
