For filing (general reference filing) David refers to 'plain freestanding files held upright by the metal sliding support in the back of the drawers of .. front opening filing cabinets', while disapproving (detesting...) Pendaflex hanging files.
My problem is that I have no clue of what is meant by free standing files. Does they require punching holes in my documents? Is it flexible?
Could anyone provide me with a picture of such a file that clarifies its fysical properties (interior, exterior)? The set of Davids files doesn't give me enough info: I still cannot see how documents are stored in those.
