formatting HD question

hey all. i have a 500 MHz G3 iBook running on 10.3. im wanting to format all the extra crap on the HD besides the OS. just curious how i would do that? i have a tiger disc and would just do the update, but its a DVD and the ibook only reads CDs, so im stuck on 10.3 for now, which is no big deal. just need to wip the extra stuff off.

if there isnt a way to do so, is there some sort of freeware out there that i could get to help me accomplish this? thanks!

do you have the 10.3 cd's? if so you can do a fresh install and wipe the hard drive. of courser before you do that back up all the documents and pictures and music you want to keep.
