Folder organizers are commonly made from plastics (including polypropylene and polyurethane), acrylic, and fabric/cardboard blends such as cardboard covered with polyester or linen.
Many folder organizers are designed for hanging letter-size folders; some larger boxes can also accommodate both letter and legal hanging folders.
Care instructions typically recommend spot cleaning or wiping plastic crates and bins with a damp cloth.
Several organizers are designed to be stacked: indexed covers or modular crate designs allow vertical stacking, and some crates can be stacked horizontally to create shelving-like storage.
Dimensions vary by style. Examples include 11.5" H x 10.88" W x 15" D, 11" H x 14" W x 18.5" D, 7.28" H x 8.03" W x 8.03" D, and 4.25" H x 9" W x 13" D.
Capacity is reported in different ways: slim folders often list sheet capacity (for example, "Sheet Capacity: 50"), while larger crate-style bins provide volume (for example, "Capacity (Volume): 30.6 Quart").
Many organizers include built-in or carry-through handles and contoured grip areas for carrying; some also use stackable or modular designs that simplify transport and handling.
Some file boxes include in-lid storage compartments for small items like paper clips, post-its, pencils, or a small calculator; desktop organizers often provide multiple compartments for office supplies and pens.
