I needed a system to sort items into numbers categories. These systems ranged from just a few pages to a large amount of data. The flexibility of these folders hung perfectly in the containers which I also purchased for a temporary holding area. Thr hanging folders will werve my purpose very well whether I only use them for the temporary procedure or convert them to a permanent file. The use of colors also helped making the filing into the folders very easy once I got into the routine of what went in each color. Thank you Staples for another wonderful product!!
