i set up MTW on my dads PC for him to get into, but i set it up thus:

F:\vanilla\Medieval - Total War\ (plain MTW+VI to copy into mod folders)
F:\NTW\Medieval - Total War\ (Napoleonic Total War)
F:\HTW\Medieval - Total War\ (Hellenic Total War)

will i have to adapt this system for BKB thusly:
F:\BKB\Total War\Medieval - Total War\ (to accomodate the BKB installer)

?

cheers
