A word of advice from someone who made a bunch of backups of my Rendo stuff a few years ago... do NOT save them as the original zip files on a multi-session CD. If at all possible, extract them all out to a dummy "runtime" folder and then burn that to the cd in a single session. You have no idea how heartbreaking it is to get to your backup zipfiles two years later and find out they're all rendered corrupt and inaccessable by the method through which you burned them to the disc. :(
