So, I am making a server for me and my friends using MCAdmin. It normaly generates a map. I made a flat .dat map with Omen, which is what MC Admin uses. But when i launch the server, it deletes the level.dat file that I made, with a randomly generated map and makes all of these double symbol label folders eg: 1c, 1d, etc. Im guessing that the problem is that my level.dat does not have all of those folders containing map info with it. So how would i add my custom level.dat to my server? Is there a program that will pre-generate the map or something?

PS if you dont know what double symbol folders im talking about, go to your save folder and see
