In using hanging folders, you mioght think about the problems and the advatnages.
Problems: they can fall off the rails, get tangled, and, the labels(if the are the stick up kind) can obscure one another unless you lay them out carefully. So if you are adding into the system, you will need to re-adjust the entire set of labels. I believe there is system available where the labels lie flat in a little plastic case at the top edge of the folder, but I think these may be $$$. Finally, if you need to use folders within hangng folders, they are made specially for this and are wee bit smaller than a regular folder. You would probably need these internal folders if you are putting irregular bits and pieces in (clippings, memorbilia, reciepts, cds) or have items that go in are hard to grasp in one hand, or if you need to remove the internal folder for refilling.
