A filing system is a method used to organize and store documents, making it easier to retrieve information when needed. It can be physical, using folders and cabinets, or digital, utilizing software and cloud storage. A well-structured filing system helps individuals and organizations maintain order and efficiency in managing their records. Common types of filing systems include alphabetical, numerical, and chronological arrangements. An effective filing system should be tailored to the specific needs of the user, ensuring that documents related to projects, clients, or financial records are easily accessible and systematically categorized for quick reference.
