compressing mutliple iso's

[lazyass100]

okay guys, this is probably really simple but im just plain uninformed.
i know how to convert iso's without any trouble but ive hit a snag, my back up for valkyrie profile is in 6 parts. can anyone help me get it into one eboot or if not, how does this work?! much appreciated!
