Fix Map File is Too Big on Dota AI Map or Warcraft 3

"The map file is too big. Please choose a different map!"
Ever found this message when try to play a map? Especially the Dota AI map which has map size more than 4 Mega. Well, if you got this message, that means your Warcraft Patch is outdated. To play Warcraft map with file size of 4 Mega or more, you must use Warcraft Patch 1.24b or above.


To upgrade your patch into Warcraft 1.24b, i recommend you to use the Warcraft Version Switcher. That is the easiest way to upgrade your patch. But if you don't want use that, you can also check this link to upgrade using another way.

Hope this post can help you fix the "The map file is too big. Please choose a different map!" problem.
