Another way of doing it (this is what I do) is to compress the Runtime with something like Winace, and tell it to make volumes. Then you enter how large each volume should be - in case of a CD: 700Mb and sit back while it compresses the files. This way you won't need 20 cd's to back up a 15Gb Runtime either. Oh and this reminds me that it's been quite a while since I last made a FULL backup of my Runtime...
