We use these folders for larger real estate transaction files, and accounting files. They are great for organizing documents and separating them into their own section. I would highly recommend using them if you don't mind paying a little more to get a good product.
Instead of flipping through a three inch file trying to find a single sheet of paper, the multi-tab files really allow you to categorize them into four separate sections - once you use them you'll never know how you lived without them!
