C:\Users\ \AppData\Roaming\Red Alert 3\Maps\.C:\Documents and Settings\ \Application Data\Red Alert 3\Maps\.The location of the RA3 Maps folder depends on what version of Windows your have installed: Red Alert 3 maps are placed in the Red Alert 3 custom fan maps folder. Each map has its own subfolder, named the same as the map, within the main custom Maps folder. seems more like a question for google, to be honest.
