This is a file system used on some CD-ROMs and DVDs. Since the
file system is supported by multiple operating systems and is more
compatible with standard unix file systems, it is also suitable for
removable USB disks. Say Y if you intend to mount DVD discs or CDRW's
written in packet mode, or if you want to use UDF for removable USB
disks. Please read <file:Documentation/filesystems/udf.rst>.
To compile this file system support as a module, choose M here: the
module will be called udf.
If unsure, say N.
