ABSTRACT:
A document file comprises a front cover, a side flap, and two end flaps all connected to a rear cover by hinges. The side flap is connected in use to the end flaps by means of tongues formed on the end flaps which protrude through slits formed in the side flap. The slits are inclined to permit relative sliding movement between the flaps to vary the capacity of the file. Similarly, the front cover can be slidably connected to the side flap by engagement between tongues on the front cover with recessed edges formed in the side flap.
