14 ULEAD BURN.NOW USER GUIDE
About file systems
When creating a new disc, you need to select an appropriate file system that will
make the disc readable on the device or operating system where the disc will be
viewed or played. Choose the file system in the
Burning Options
dialog box
before burning the disc. (Click
Burn disc
on
the
Toolbar
.) The file systems
that are available include:
•
ISO 9660
ISO 9660 is a cross-platform file system that is readable on Windows,
Macintosh, and Unix. When you create an ISO 9660 disc with
Joliet
extensions,
names of files/folders burned onto discs can have up to 64 characters in length.
Burn.Now allows ISO 9660 to be used as the file system for data and MP3 discs.
•
UDF 1.5, 2.0 and 2.01
UDF (Universal Disc Format) is a file system developed by OSTA (Optical Storage
Technology Association). There are various UDF versions. UDF 1.5 (readable on
Windows 2000 and above) and higher versions (readable on Windows XP and
above) support random packet writing and allows over 4 GB of data to be burnt
onto a DVD disc. (See
“Appendix B: Glossary”
for information on random packet
writing.)
•
UDF 2.5
UDF 2.5 file system provides the
Mirror UDF metadata
option storing 2 copies
of your data structure in physically separated areas on a disc. This enhances the
integrity of the file system data on a disc.
•
UDF 2.6 Low
UDF 2.6 file system supports the Pseudo OverWrite (POW) mechanism for
recording on write-once discs and drives such as BD-R (Blu-Ray Disc-Write
Once). The POW mechanism allows write-once media to function like a
rewritable disc. This file system also increases compatibility between consumer
electronics video recorders and computer systems.
•
UDF/ISO 9660
UDF/ISO 9660 (also known as UDF Bridge) is a combination of two file systems:
UDF 1.02 and ISO 9660. Discs burned with this file system can be read by
Macintosh and Windows.
