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
