Abstract

File system operations include data operations and metadata operations. Data operations act upon actual user data while metadata operations modify the structure of the file system, like creating, deleting, or renaming files, directories, etc. During a metadata operation, the system must ensure that data are written to disk in such a way that the file system can be recovered to a consistent state after a system crash. In this paper we look at some most notable techniques which ensure reliability of disk file systems against system crashes and failures.

Abstract

FAT file system is the most primitive, compatible and simple file system which still sustains in this era on digital devices, such as mini MP3 players, smart phones, and digital cameras. This file system is supported by almost all operating systems because of its simplicity and legacy. This paper presents review of the basic design technique, constraints and formulas of the most important and building block data structure of FAT32 file system; the FAT data structure.
