The 'import' folders are examples showing how you load (import) files produced with mapscape into DBPro or DarkGDK - I can see how you got confused, it's not short for 'important'

The actual program is 'Map Scape.zip'

Does that mean you're looking for a 2d level editor? If so, MapScape won't be much help, that's a 3d map editor
I'm sure there are others, but the only 2d editor I know about is one I saw a while back by ShellfishGames, which looked pretty interesting!

To be honest though, I think that might be more of a complete engine than just an editor, and I'm not sure if it's designed for top-down games only - could be worth checking out if you're looking for 2d though
