The only problem is that those kinds of folders are not commonly used in Germany. I think I never saw a folder like that before I started using computers.

The word that is used in Germany to refer to folders („Ordner“ in German) actually refers to ring binders. Yet I had never a problem dealing with folders on computers, even though the visual metaphor was unfamiliar to me.
