Expanding files are an convenient way to store and move data that is both tidy and secure. We feature both opaque and semi-transparent expanding files in a wide range of colors. The files are made from high-density polypropylene. They're lightweight, environmentally friendly, scratch and moisture resistant, and super durable. The folders come with and without handles, two different designs, and your choice of 3, 6, or 12 inner pockets. Color-coded tabs can be attached to the inner pockets for easy classification of your data.
