Gimp settings folder location

[js017]

So how do I change the location of the ".gimp-2.8" folder from "C:/Users/Administrator" to "C:/Users/Administrator/AppData/Roaming"? I've tried to change the folder location in gimp's settings, but it keeps creating the ".gimp-2.8" folder in "C:/Users/Administrator". Could you please provide detailed and easy to follow instructions of how to do that? Thanks.
