How come my map is so huge (filesize)?

I have made a lot of maps, and for some reason my new map, Castle Chaos. It is 826 kb! Thats huge! And I look at other maps I have Dled and they are 45kb-150kb.

My map is not that big, it is 85x83 playable.

It does'nt have that many doodads either.

Is there a way to reduce the size of my map. Theres no way I can release it when people have to DL a 800kb+ map.

Please help.

Thanks

You most likely have custom music/sounds attached to it. Take them off and all is fine.

delete all the unused units

dammit, it was my loading screen.

I hate to take that off...

now its 64 KB

thanks
