Size (Weight) Map

Which is the max size that has to have a map to be played in lan?
I did a map and which was my disappointment on having seen that it was saying to myself that it was too big (20 mb)
There is some way or some program that compresses the files to reduce the size program?
Thank

its 4 mb battle.net wont accept heavier ones

hope it helps you

Why is it so heavy?

If it's audio, you can compress your files. It won't make them sound as good, but they won't take up as much space.

I know one trick to nearly cut the size in half is to make it mono.

Optimize your map by either compressing (read tutorial) or removing unneeded files (Imports).
- Optimize triggers. Use loops instead of repeating triggers for each person.
- Use variable arrays stead of just variables for each person.
- Don't place a mass amount of units on the map. Each unit's location and facing direction is stored on the map. If you need to create a large number of units use triggers maybe.
- Same for Doodads, Using less will mean the map will need to save less.
- If your good at triggers you can use them to randomly generate doodads for an area.
- The larger the map side the more map land info the map has the store. Use the smallest size possible and optimize the space you have by using boundaries to separate areas and use triggers (camera) to stop players from looking outside the area.

-For B.net (online play) make sure your map does not lag, people really hate maps that lag.

Here's an example of a tree generator I made a while ago. I used custom tree models on this but you in game doodads, which will save size. Give credit if used.

Thank you very much
I will have to do a miracle to solve this. Sniff sniff
