Abstract: The present invention consists of a particular separate identifying tab which is designed to slide or stay put on the edge of a compatible file folder for the purpose of maximizing the visibility of all tabs in a file drawer. Stability of the tab on the folder edge is obtained by means of a tab made of hard laminated cardboard (or any other material with the same properties of friction and lightweight); a fork base whose sides are proximate enough to maintain a grip by friction on the folder edge; and a thin, sturdy, and pliable pressure-sensitive low-tack adhesive flap extending from the fork base, which flap, when applied to the surface of the folder, reinforces the stability of the tab on the edge of the folder. Mobility of the tab on the folder edge is obtained by peeling the flap from the surface of the folder and applying moderate pressure against the side of the tab in the direction desired.
