HaloMods "Classic" Read-only Archive

Hey, I just got done making my first map, and i think it looks pretty good. I exported it to a .jms, and now im on to trying to use tool. The problem is when I open command prompt it gives me the usual microsoft windows xp blah blah blah and then it says

C:\Documents and settings\Thomas(User name)>

and in every tutoial ive looked at it starts with something like

C:\Program files\Microsoft Games\Halo Custom Edition>

I was wondering if theres a way i can change what mine says to what the above one says?

I hope I explained this well, and any help would be much appreciated.

Just type this:
cd..
cd..
cd Program Files
cd Microsoft Games
cd Halo Custom Edition

I get "the system can not find the path specified". Sorry, I am a newb to Command prompt.

Edit: I think I got it working... not sure why this didnt work before.... Thanks Dan, I owe you one.

type:

cd\Program Files\Microsoft Games\Halo Custom Edition

then hit enter.

or you cud just copy ur cmd.exe into your HaloCE root directory and open it from there. it'll be default at ur root so no need to navigate
