[mkgmap-dev] Maps in *.gmap format installation directory

Is there a unique directory where maps in *.gmap format can be installed? I would like to change my current installers to use gmap format instead of the old format, but I don't know what is the right directory to install them. In my XP virtual box if I copy gmap folder in c:\archivos de programa(program files)\Garmin\Maps maps are read by MapSource, but not by BaseCamp. If I copy gmap folder in C:\Archivos de programa\Garmin\Basecamp\Maps then they are read by BaseCamp, but not by MapSource. And what about more recent versions of Windows?
