Right click desktop and create a new folder.This folder is to contain the super hidden folder in case you lose it's whereabouts on desktop.
Open the new folder and create another new folder within.
Right click this inner folder - properties - customise - change icon.Scroll along the icon list until you see a blank space between the icons and select it - OK - apply out of it.
Right click the invisible icon - rename.Hold Alt key and type 255 from the numlock numbers pad (right side of keyboard) - enter and you should have a super hidden folder.
Go back back to desktop and delete the original created folder and that's it.
What use is it, probably useless but at least I know how to do it now.
