Choosing a file system

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 operating systems that include Vista, 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 Vista 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

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 file system/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.
