What is UDF?
------------
UDF (Universal Disk Format) is a new file system, with support for the current
generation of optical discs such as CD-RW, DVD-ROM and DVD-Video. Standard
CD-ROMs are usually formatted using a file system called ISO 9660. Windows and
Mac computer systems can read ISO 9660 CD-ROM and CD-R discs because they have
built-in ISO 9660 Readers. However, ISO 9660 has certain limitations which make
it inappropriate for DVD, CD-RW and other new disc formats. UDF is designed to
address these limitations. Specifically, UDF allows files to be added to a CD-R
or CD-RW disc incrementally, one file at a time, without significant wasted
overhead, using a technique called packet writing. Also, UDF allows for the
random erase of individual files on CD-RW media, freeing up space in the
process. ISO 9660 can't handle this.
UDF is also better suited for DVD, because it has better support for
large-capacity discs.
UDF, like ISO 9660, allows the same CD to be read on different platforms.
For example, a file could be written using a PC, then read back on a Macintosh.
UDF file format is able to maintain Macintosh file attributes (icons, resource
forks, and file types). ISO 9660 cannot do this.

What is a UDF Reader?

A UDF Reader enables MultiRead CD-ROM drives to read UDF formatted CD-R and
CD-RW media under Windows 95/98/NT4.0. The UDF Reader for Windows is called
UDF Reader Driver.
