File holder
 A file folder includes a first panel, a second panel connected with the first panel along a fold line, a flap cut out from the first panel, and a C-shaped clamp defining a clamping mouth thereon. Each of the first and second panels defines an internal surface opposed to each other. The flap is formed from the material of the first panel and is secured to the second panel along a hinge line coincident to the fold line. The flap is pivotal about the hinge line and can be folded to partially cover the internal surface of the second panel. One end of the clamp is pivotally connected with the second panel near one end of the hinge line. The clamping mouth of the clamp faces the hinge line of the flap such that the clamp can be pivoted between a first position clamping the flap together with the second panel and a second position releasing the flap and the second panel. Loose papers can be placed on the internal surface of the second panel having one edge of the papers partially received between the flap and the second panel. The clamp can then be swung to clamp the papers together with the flap and second panel such that the loose papers can be held and secured within the folder without the need to punch holes on the papers.
