The hook units is affixed to each of the upper exterior corners of each file folder on one file folder cover, and the loop unit is affixed to each of the upper exterior corners of each file folder on its second cover. When the second cover of a hanging file folder is brought into storage position adjacent to the first cover of a second hanging file folder, the fastener pairs releasably lock to prevent the juxtaposed folders from separating.
