Abstract: A method for converting the usual report cover or binder into a unit which is conveniently and easily readied for storage in a suspension type filing system. The application discloses both a suspension element for use in putting the method into effect, and a combination unit including a binder in which two such suspension elements are slidingly mounted in the spine of the binder for selective manual movement relative to the spine between a retracted position within the spine and an extended position extending beyond the ends of the spine for engagement with spaced support rails of the type on which the binder will be placed for filing purposes.
