I purchased the bag after seeing it used by a friend, and loved the size of it. His complaint was the file folder rails not staying in place, which caused his files and forms to constantly fall to the floor of the bag. Being mechanically gifted, I saw that this was an easy repair. The metal rails have 4 tabs that slide into 4 pouches. The bag walls are lined with plastic. I simply placed the rail tabs into the pouches, drilled a hole through each one through the bag, then used black pop rivets to secure it. Works perfectly securing the rails and looks fine. Problem solved. This is something the manufacturer should do during construction. The bag floor should also include a plastic line floor, and a 2 more interior partitions should be included or sold separately. All in all, I love the bag.
