I'm working on a Multiboot DVD and I am using CDImage to create the ISO file. The content of my DVD is getting bigger and bigger. I'm finding that it takes a very long time to test changes to the ISO because it takes a very long time to create a new ISO after I have just made changes TO JUST ONE FILE! I was wondering if there's a program that can detect changes in an a directory and compare it to the ISO and only update the changed files. This program doesn't have to be able to "optimize" the iso because I can do it later with UltraISO.

Edit: Hopefully this program is command line based or you can save the configurations.

using easyboot doesn't take much time to create my DVD image

try MagicISO

There are a bunch: MagicISO, ISO buster, PowerISO, and my favorite is UltraISO.
