I have plasma desktop but I can't seem to find a way to get the plasmoid to point to nautilus. It always asks how to open filetype "file:///". The fact this is a protocol even weirder.

How did you ?
With the Kubuntu/KDE the plasma widget folderview (Folder Views) /1/ is using the system's default application. System Settings > Default Applications and System Settings > File Associations.
