How do I play all of Civ IV at once?

[enahs.g]

When I open civ 4 it just opens civ 4, when I open warlords, it just opens warlords, and when I open beyond the sword, it just opens beyond the sword.

Is there a way to play the game with all the games together?

(note: I know Civ 4 colonization is a separate game, I don't expect that game to be combined).

[~= K@l@ys =~]

As Warlords and BTS are both Civ4's expansions, you're already playing Civ4 + BTS, or Civ4 + Warlords. But sorry for that, you won't be able to mix the 3 of them. ^^
(My point of view is that BTS is enough to have great fun, greatest expansion ever =D)

It appears that Beyond the Sword includes all of the gameplay elements from Warlords except for the scenarios, so if you want to play a game of Civ IV with all of the added features, play Beyond the Sword. If you just want to play the Warlord Scenarios, then you have to play Warlords.
