These hanging folders are a lifesaver! I work for a real estate office, and we have files on files on FILES. Without these great hanging folders, the filing cabinets would be an absolute disaster! The hanging folders help me to differentiate between files, while at the same time keeping all my files standing up and nicely organized. I like these folders so much that I've started using them in cardboard boxes, just to keep everything organized no matter where my files are being stored. Thank you Smead, for making such a strong, reliable folder!
