I just went out to the local mountains today, in fact. On my person were a Greco Explorer (full tang, 9.5" fixed blade), Leatherman Supertool 200 and RAT/Ontario folder. So, yep, I always have a folder on me in the wilderness to supplement my fixed blade.
My thinking is, I carry a folder in my pocket for EDC when driving to the wilds, so why not bring it with?
