Abstract
Abstract An indexing system for file folders of the type having a tab along one edge includes a pattern of variable length fields formed on the tab. Each field carries indicia of a size proportionate to the field length. The indicia are visible along the edge of a folder placed in storage. When a series of folders are juxtaposed the indicia combine to form a visual pattern which directs a user's eye to the proper location for removing or replacing a particular folder. The indicia comprise color-coded bars which readily create the visual pattern.
