These folders are so similar, they can be filed together with no problems. The colors also make them so different that they won't be confused as far as filing goes. Inside each file folder, 5 different mini folders allow organization of whatever that specific folder is for. And best of all, nothing will ever get from one folder to the next in a big mess of papers because the snap at the outside of all 5 folders is too strong for them ever to come open accidentally. Happy filing!
