i want to edit this map in which folder is it

Hello all. This is my world map. It is designed to be fun to play rather than geographically exactly accurate. There are eight players- the USA, Europe, Russia, China, India, Australia, South Africa and South America. To make the Pacific interesting, if you get to be the USA you start on both the east and west coasts of North America (as linking the map from east to west is not yet possible). I have created important cities (which cannot be destroyed) as well as neutral industrial areas to conquer. I have put lots of useful raw materials in the middle east and old Dutch East Indies to make those areas worth conquering. Have fun! At some point I need to do a Europe map.
