These fileback fasteners are perfect for adding and changing files, especially adding new sections, without disturbing the original file organization.  Fileback Fasteners are compatible with any 2 pronged metal fastener.  Simply slide the new fastener hinges on the current folder prongs and put in the new section.  You will be able to add and remove material directly into the new section without having to fumble through all the previous documents!
