Crossfire EU Tactial maps question

Where can i find the the tactical maps in the folder of Crossfire on my computer?
I only find the minimaps, but not the big tactical maps... :s
I want to delete them or cut them because my key to walk (µ) is the same as the hotkey to show the tactical map during the game. And i can't change the hotkey from showing the maps.
Somebody help me ? (:

And sorry for my bad English

If you are in game, you can press the hotkey to view the whole map of the map where you're playing in. Actually the floor map..
