A document folder is a versatile tool designed for organizing, storing, and protecting papers and documents. It typically consists of a lightweight, flat enclosure made from materials such as plastic, cardboard, or leather, and may include features like pockets, fasteners, or dividers. Document folders are used in various settings, including offices, schools, and homes, to keep paperwork neat and easily accessible while preventing damage or loss. They come in different sizes and designs to accommodate a wide range of document types and organizational needs.
