Hanging file folders are a colossal pain. Designed to hold open sided manila folders inside of an open sided larger folder, they effectively achieve a srate of perfect disorder. There has to be a better way, and in my office, these are the ticket. Because the bottoms can be expanded to rest flat and the sides are closed, they keep my documents neat. Nothing spills out of the sides, and as they fill up, they don't bow outward. I eliminated my hanging folders completely and exclusively use these. My file cabinets have the metal brace that slides forward to hold the files in place, so these don't move or fall backward. At last, no more messy files! I can't say that these are better or worse than similarly made folders, but they have certainly solved my file problems and I would highly recommend them.
