Hi Emile,
just copy the bdpzapper.exe and paste into your CFS3 install. Personally, I prefer the zapper originally used in MAW, because it deletes ALL the bdp files within the entire install. The later ETO version deletes from aircraft, guns, weapons and vehicles, but not from ships, buildings and possible other folders I've forgotten??
However its your personal choice - you may prefer the ETO BDPzapper.exe.
Sorry I don't have my cfs computer open so I cannot give you the exact name of the earlier version (which may have orginally been a .bat file?)
