simple, yes this is a very late post but, if ur on windows type in %appdata% on ur task bar. Then open up .minecraft folder. Inside there should be a 'saves' or save folder. Open that. Once opened, place the downloaded file into it and open it. It should extract it and turn the file (map) and turn into a folder. Once thats done you just need to open up minecraft. No mods are needed.
