I remember using .zelda files...that was just bothersome.
I normally save my levels as .graal, because for some reason, .nw lag offline sometimes

(not always though).
saving files with different extensions can help organize things too...like
cave1-1.quest
mike1-1.house
dustari1-1.castle
world1-1.field
If i could start over...that's what i would do, but, I'm not gonna start over
