This is entirely off-topic, and could be continued in wikitech-l, if you're really eager to tell how you modify compressed files "in place". ;-)
You can decode bzipped files an arbitrary block at a time (which makes reader apps surprisingly viable on devices with only a few gig of flash). Modifying them ... that's a bit like fun!
