I;m trying to make a map but the hgt converter doesnt seem to be working. So all I have to do is go to command prompt and type in that stuff you said. The instructions says to open up my map folder. What do you mean by this do I type in the path name in command promt or do I just open it like a normal folder. When I didn't type in the path name it just didn't work nothing happened the hgt file didn't get created...
