Conﬁguring the File System and File Names

To conﬁgure the disc’s File System and File Names:

1 In the Layout Editor directory area, select the Disc folder.

2 In the Property Browser, double-click the Disc Information folder.

3 Set the File System menu to one of the following options:

DVD Video Uses the UDF and ISO 9660 ﬁle systems.

DVD Video with Joliet Adds the Joliet extension to the ISO9660 ﬁle system, allowing

ﬁlenames of up to 108 characters, including support for Unicode and non-English

characters. The Mac OS can read Joliet discs but will shorten ﬁlenames to 30 characters

and not display non-English characters. DOS systems will shorten the ﬁlenames to 8.3

characters and also not display non-English characters.

4 Set the File Names menu to one of the follow options, which will determine how

ISO 9660 names will be displayed:

MS-DOS (8+3 characters) Allows ﬁlenames with up to eight uppercase alphanumeric

characters, followed by a period (.), and a three-letter extension. This format supports

the tilde character (~) used by later versions of MS-DOS to support long ﬁle names.

Restricted (8+3 characters) Comparable to ISO 9660 Level 1, which allows ﬁlenames with

up to eight uppercase alphanumeric characters, followed by a period (.), and a three-

letter extension.

Unchanged (Max 30) Comparable to ISO 9660 Level 3, which allows ﬁlenames of up to

30 characters using any of the ASCII characters.

All DVD discs contain ﬁlenames using both the UDF and ISO 9660 ﬁle systems. In addition,

if the File System is set to “DVD Video with Joliet,” ﬁlenames based on the Joliet ﬁle system

will also be included.

Files residing in the video and audio zones (the VIDEO_TS and AUDIO_TS directories) will

always use MS-DOS (8+3) ﬁlenames.
