Maybe theres an ARCH00 tool that opens up the arch00 files which probably contains the files. I only know of 1: Aplha 05 Arch00Viewer
I don't know of a particular application for doing that (like GCFScape for Source or XCC for C&C) but I'm pretty sure the fully installed F.E.A.R. SDK can handle that. You can glom onto it here on Filefront (elsewhere too, but I'm new so I feel a little better plugging the site. That and it's quality here. No damn 40-minute waiting lists like FilePunket.)... don't recall the size but it'll be listed on the front page list at the F.E.A.R. Filefront hosted site.
