File Concept The file is a collection of related information that is recorded on storage device. Directory contains link / pointer to first block of a file. The File system takes care of the following issues. This access method is the most primitive one. Helps OS to standardized I/O interface routines for user processes. The random access method is also called direct random access. The records need not be in any sequence within the file and they need not be in adjacent locations on the storage medium. This increases efficiency, as the right user receives the correct file. It is the process of maintaining folders, documents and multimedia into categories and subcategories as desired by a user. Every File has a logical location where they are located for storage and retrieval. A file management system is used for file maintenance (or management) operations. A source file is a sequence of procedures and functions. An object file is a sequence of bytes organized into blocks that are understandable by the machine. Files could be arranged or more complex structures to reflect the relationship between them. Minimizes the chances of lost or destroyed data Helps OS to standardized I/O interface routines for user processes. Unix, MS-DOS support minimum number of file structure.
