Abstract: A large-capacity file folder that includes a support structure including first and second walls in pivoted association for pivoting between closed and open positions. The first and second walls define an angle therebetween, and when the first and second walls are in the open position, the angle is greater than 90°. The file folder also includes an expandable file portion that includes an expansion-limiting member connected to the first and second walls and configured for limiting the pivoting of the first and second walls to the open position, and a plurality of divider panels disposed between the first and second walls and connected in series to the expansion-limiting member to define pockets therebetween. In the closed position, the pockets are collapsed, and in the open position, the pockets are expanded with the divider panels pivoted with respect to each other.
