Abstract
A stair-step, expandable file folder is disclosed, in which each pocket in the folder has the same depth, rather than the back pockets being deeper than the front pockets. The folder is formed from a unitary insert divider web. The divider is suspended above the floor of the folder by tabs which are affixed to the folder walls and by attachment to the inside from and back panels of the folder.
