Since the 10 file system is supported by multiple operating systems and is more 11 compatible with standard unix file systems, it is also suitable for 12 removable USB disks. Say Y if you intend to mount DVD discs or CDRW's 13 written in packet mode, or if you want to use UDF for removable USB 14 disks. Please read <file:Documentation/filesystems/udf.rst>. 15 16 To compile this file system support as a module, choose M here: the 17 module will be called udf. 18 19 If unsure, say N. 20
