The presentation and storage folder (10) allows filing of transparencies in a normal binder (1) and in addition allows projecting these on an overhead projector (2) without detaching these from their binder. The folder is composed of at least three leaves the first of which (11) allows to file it in a classical binder, the last (13) being composed of the transparency or of a transparent pocket which can contain the transparency proper whereas the leaf or leaves in between (12) allow to unfold the folder and place the transparency on the glass of an overhead projector without needing to detach the folder from the binder.
