anyways, I was checking out all the halo mods elite stuff and downloaded some skins and mods. and well, they are rar files, but here is my question...how on earth do I put it into halo (or the halo custom edition I don't really know) so I can play around with them and use them?

and if it helps, I am using a pc and using the pc version of halo. oh and one of the files are a zip file and it says it is a unknown file
