Map downloading is similar to downloading presets, yes. There is a different as to where ye put the map files, though. When opening the zip file, most of the contents will be going to the "exports" folder. The download should specify what should be going in what folder, but if not, feel free to send a screenshot of the contents of the download, and I'd be happy to explain where to put everything.
I hope this answers y'er question. If not, I'm terribly sorry. I may 'ave read it the wrong way.
