UDF

In Zeta you can mount UDF volumes just as you would mount any other volume on your system, and create UDF volume images for burning to CD or DVD. The udf/i-udf-ds will let you mount and access most commercial read-only DVDs and most custom burned, single- and multi-session UDF DVDs and CDs. (Note that Tracker lists all sessions on the disc; the bottommost volume in the list is the most recent). The makeudfimage will let you create UDF 2.01 and 1.50 images containing plain files and directories, much like an iso9660 image made with mkisofs, but with better support for long filenames and extended character sets.

The UDF integration excists of the following files:

- udf: UDF filesystem add-on
- i-udf-ds: UDF DriveSetup add-on
- makeudfimage: command-line program for creating UDF volume images that may be burned to a CD or DVD.

How To Burn a UDF CD

1. Put all the files and folders your want on the CD into a single folder somewhere. Name the folder udf, the full pathname for that folder would then be /boot/home/Desktop/udf.
2. Create a UDF image from the files and folders of interest (a UDF image is a single file that can be written directly to a CD to create a UDF filesystem on that CD which contains your files and folders). You need to choose a name for the image file, as well as a volume name that will be displayed by Tracker when you mount your soon-to-be-burned CD.
   Let's say you choose /boot/home/Desktop/mystuff.udf as the image name and My Stuff as the volume name. You would then run makeudfimage from a Terminal prompt as follows (note that this should all be on one line, even though your viewer may decide to word-wrap it):
   makeudfimage /boot/home/Desktop/udf /boot/home/Desktop/mystuff.udf My Stuff
   This should merrily add all your files and folders to the image and proclaim success at the end.
3. Burn the image to a CD. You can for instance use CD Manager, but there are other ways to do it as well. To burn the image, place a blank CD in your burner, and then start CD Manager. Click the Tools menu, and choose Write Data CD Image File... . A window titled Start Data CD Image File Recording should appear. Click the Browse button and select your image file (in our example: /boot/home/Desktop/mystuff.udf) from the Select Image File dialog window. Change the selected Action from Write Simulation to Write, and then click the Start Writing button. CD Manager will then burn your image to the blank CD. When the recording is done, close CD Manager.
4. Mount the CD

UDF or iso9660 ?
The DriveSetup add-on, 'i-udf-ds', is named as it is with an 'i-' prefix to put it alphabetically before the iso9660 DriveSetup add-on. But if you insert an UDF/iso9660 hybrid disc in your computer, the UDF add-on will get first dibs at identifying the disc. This is usually desirable, as UDF, as mentioned above, has better support for long filenames and extended character sets. If, for some reason, you'd prefer to default to iso9660 in those cases, just rename 'i-udf-ds' to 'udf-ds'.
