ABSTRACT:
Disclosed is a file for holding various kinds of documents or letters, which is constructed essentially of a rigid rectangular main plate, a cover and soft pliable portions provided along at least the longitudinal side edges of the main plate. The cover sheet is dimensioned so as to cover the main plate and the soft pliable portions and is fused to the pliable portions and bottom end of the main plate. The top end of the cover sheet is left separable from the main plate so that papers or letters can be inserted or removed. The structure of the file is such that when the file is empty, the cover sheet is closely adjacent the main plate since no separation member is disposed between the main plate and the cover sheet. This makes the file very flat and convenient to transport. Nevertheless, when it is desired to open the file, the cover sheet can merely be pulled forwardly, whereby the pliable portions bend forwardly and papers or letters can be inserted into or removed from the pocket formed between the main plate and the cover sheet.
