By default, WebCD Packager writes to CD on-the-fly, that is, directly from the
original files (in the folder location specified on the Build Options dialog).
WebCD Packager can create a real ISO 9660 image and then write it to your CD-ROM. To do this, use the Create Pre-mastered ISO
Image in Folder option on the CD-Recorder Options dialog to instruct WebCD Packager to create the real ISO 9660 image before
writing to CD.
Warning The ISO 9660 image is as large as all the files used to create it,
therefore, you will need at least the amount of hard disk space it would take to make a
copy of all the files that will make up the CD-ROM. Specify a temporary folder
location that has adequate space.
