It is that map (those maps) that I am trying to locate in windows. The ones that are named and listed ONLY under Map Editor/Load.
I have searched OS(C:) using file names, as best I can tell no ability to provide city name is available in the Editor, to no avail.

Those are in the C:\Users\%username%\AppData\Local\Colossal Order\Cities_Skylines\Maps folder, or at least that's where they should be.
