Fellowes Expanding Files

Expanding file folders are a practical way to store large volumes of paperwork in one secure place. Designed with multiple internal compartments and labelled pockets, these expanding files keep documents separated, clearly labelled and easy to access, making them ideal for busy offices, schools and home working environments.

Our range includes A4 expanding file folders compatible with standard filing systems, along with selected foolscap options. Whether you need plastic expanding file folders for durability or lightweight card expanding document wallets for everyday filing, we offer solutions suitable for both short term document organisation and long term archive storage. As part of our wider range of filing and archive supplies, you can also explore document organisation solutions.

Available in a variety of pocket capacities including 6, 12 and 13 part expanding files, many designs feature indexed tabs such as A–Z or 1–31 for structured document sorting. Durable outer covers help protect paperwork, while secure closures keep contents safely contained when stored on shelving or transported between locations. For additional structured storage, consider pairing your expanding file folders with suspension files or box files.

From accordion file folders for portable organisation, to expanding case files for structured office filing, our expanding files are designed to support efficient document management across professional environments in the UK.
