Abstract: A suspended file folder assembly is made from thermoplastic material and uses a thermoplastic sheet folded along at least one score line to define a folder, which has a retaining portion at upper edges thereof. A support bar, having a cavity in a bottom portion thereof and being substantially symmetrical with respect to its longitudinal axis, mechanically engages with the retaining portion. This weight-bearing interlock distributes the load of the folder along the length of the cavity of the support bar and the upper edge of the sheet. The support bars have notches therein for engagement with conventional suspension rails as well as at least one indentation for accommodating an index tab. A rotatable index tab, or clip tab, is also provided with a lower part, including outwardly extending leg-like extensions, that is complimentary in shape to the support bar and attachable to the support bar.
