The map is a raster map and what they forgot to do (maybe they don't have the tools to do) is, to remove all the noise from the scanning inside the coloured areas. So all water, meadows a.s.o. require a much bigger amount of memory. You even can see the different types of blue e.g. in the Black Sea from the different scan runs. Thats why this map takes such a big amount of memory.The degree of detailisation however is very high, it looks like 25K. So if you need a detailed topo map of Bulgaria you will learn to like the big size of the map. One further disadvantage is that there is only one in one scale included. I found it can be used only between 700m up to 150m zoom in Mapsource (with highest resolution) - below and above gives useless maps.
