Abstract
Abstract An improved accordion-like file has a plastic cover and envelopes, the plastic cover is integrally formed as a foldable multiple-sectioned cover and folded inward on one end to form a folded piece and a block piece with a foldable mechanism therebetween. By moving the block piece outward and securing to the folded piece with a set of reusable tape thereon, the accordion-like file can be completely extended and contain documents with more space.
