HaloMods "Classic" Read-only Archive

Ok, I've already got Halo 2 on my Hard Drive, but I haven't got enough money to upgrade the Hard Drive, so for a while, I have to make do with the space I've got. However, to keep it as free as possible, what files do I absolutely positively need in order for the Halo 2 MULTIPLAYER ONLY to work?

Right now, I've got the following files on the Xbox for Halo 2, please let me know if I can delete any of them.

bink (folder)
- attract_60.bik
- attract1.bik
- credits_60.bik
- intro_60.bik
maps (folder, I'm not gonna list all of them)
media (folder)
- ArialUni.Ttf
- command line.txt
- dlcustom.rdf
- dlcustom.xpr
- dlres.rdf
- dlres.xpr
- Sound.xsb
- Wave.xwb
(no longer in media folder)
dashupdate.xbe
default.xbe
downloader.xbe
update.xbe

I'm mostly concerned about the .bik files, those all take up a lot of space, and deleting them would free up some room on the Hard Drive.

u dont need the bink files

You can also delete all maps on your xbox that have a number in front of them.

Only default.xbe is needed for the xbes.

yeah, deleting campaign maps will free up alot of space, though make sure you keep the shared.map, mainmenu.map, etc maps.
