Have you ever wanted to burn a cross-platform CD on an OS X Mac and find you don't have Toast or Nero installed? DISC-O is a freeware utility for OS 10.3 that can create and burn ISO CD disc images. Here's what the main application window looks like:
To create a new ISO disc image, type a name for the image in the "ISO Image Name" field, then select a source folder using the "Select folder..." button. DISC-O creates an ISO image at the root level of your boot volume. So, if a user entered "disk1," DISC-O would create the "disk1.iso" image as shown below:

DISC-O can also be used to burn other ISO images. Simply place the image at the root level of your hard drive, type the image name in the "ISO Image Name" field, and press the "Burn" button.
DISC-O loosely enforces the naming conventions in the Joliet specification with RockRidge extensions. This means you can't use illegal characters in your file or path names. DISC-O does not enforce directory tree depth limitations. The next version of DISC-O will support the conversion of .dmg to .iso files.
