The concept of a file is central to the effective use of a computer system. A file is generally loosely defined as a collection of related information such as students records employee database.

Users and programs simply access the files by the name, and the file management system handles the details The file management system identifies and manipulates files by the names provided by their users determines the physical requirements of the file,  allocate space for it, stores it in that space, and maintains the information about the file so that it may be retrieved partially or in full, later. The file management system keeps track of the available space on each device connected to the system. The  user and the user's program need not be aware of the underlying physical storage issues.
