A sliding accessory may be mounted on a rail of a file folder, binder, sheet protector, divider, or other device. The accessory may be initially provided on a printable sheet, and may be provided with one or more fold lines that enable the accessory to be folded into a desired configuration. The fold lines may also be used to form a male portion that may be inserted into the rail of the file folder for attaching the accessory to the file folder. The male portion may be provided on one or two sides of the accessory depending on a rail configuration of the file folder. The male portion may have securing portions that interconnect with securing edges of the rail of the file folder. The securing portions and securing edges interconnect in such a manner that enables the accessory to be slidably moved along the rail. The accessory may be produced from a printable sheet having one or more die-cut accessories formed therein.
