Easily stuff large and bulky files, medical charts, product manuals and more into our reinforced 4’’ expanding filing folders, designed to help you keep your important documents conveniently organized. Conveniently organize a large number of files for a single category in one file folder due to 4’’ bottom square construction with thick cardboard support insert that will support hundreds of files at once. Say goodbye to overflowing hanging files that clog your file cabinet and prevent it from shutting! Our square bottom design allows large files to sit flat and not stick out of the top of the file, as tends to happen when you use standard V-shaped hang files. Designed for organizing your home office or office filing cabinets, this bulk pack of 25 extra capacity folders comes with 30 plastic tabs and cardboard supports.
