King's Bounty: Crossworlds - Mapmaking

This was discussed on the forum, I need to search... And also, sourcemedia seems to weigh as much as 14 GB!

They warned about the large size in the manual. I'll search where it is on the forum. But it seems to me that even on my computer, such a file will take a whole day to download :(.
