The structure and logic rules used to manage the groups of data and their names is called a "file system." There are many kinds of file systems, each with unique structure and logic, properties of speed, flexibility, security, size and more. These properties comprise with capacity, speed, access methods (Sequential or random access method) and data transfer rate.
