boxes for files

File boxes are made from both rigid and soft materials. Common rigid materials include plastic and steel; common soft or lightweight options include cardboard, paper, polyester fabric, linen covers, and polyurethane finishes.

Sizes vary by style. Heights in the set range roughly from 4.25" to 14", widths commonly fall between about 9" and 14", and depths are typically around 11" to 18.5". Choose shallower boxes for single-folder storage and taller/deeper models for larger or bound documents.

Many of the boxes are designed to accommodate letter-size hanging folders, and several items in the set explicitly state they also accept legal-size hanging folders.

Closure styles include open-top designs, lidded boxes with snap or button closures, latch-equipped lids, and some secure options with lockable lids or combination locks.

Many file boxes include carrying features such as integrated handles, carry-through grips, or lightweight construction to make it easier to move files between locations.

Several designs are stackable or modular: some boxes and crates are built to stack vertically, while others can be arranged horizontally to form shelving or modular storage configurations.

Common organization features include rails or frames for hanging folders, indexed or labeled covers, in-lid compartments, internal pockets, and card or mesh slots for small items.
