A file folder is a flat, folded piece of paper or plastic used to organize and store documents. It typically has a tab for labeling, making it easy to identify the contents. File folders come in various sizes and colors, allowing users to categorize and manage paperwork efficiently. These folders are commonly used in offices, schools, and homes to keep important papers, such as reports, contracts, and notes, in one place. They help reduce clutter and improve organization, making it easier to find and access information when needed.
