What is the main purpose of a file system?

A file is an organizational form of information. It is a set of information with an identification name stored in auxiliary storage. The file system is a system used to manage the storage, retrieval, update, sharing and protection of files. When operating on files, they are all based on their file names. Therefore, the main function of the file system is to access files by name.

The file system is the method and data structure used by the operating system to identify files on storage devices (commonly disks, but also solid-state drives based on NAND Flash) or partitions; that is, the method of organizing files on storage devices . The software organization responsible for managing and storing file information in the operating system is called a file management system, or file system for short. The file system consists of three parts: the file system interface, a collection of software for object manipulation and management, and objects and attributes. From a system perspective, the file system is a system that organizes and allocates the space of file storage devices, is responsible for file storage, and protects and retrieves stored files. Specifically, it is responsible for creating files for users, storing, reading, modifying, and dumping files, controlling file access, and revoking files when users no longer use them.

In a computer, a file system is a system for naming files and placing logical storage and recovery of files. DOS, Windows, OS/2, Macintosh, and UNIX-based operating systems all have file systems in which files are placed somewhere in a hierarchical (tree-like) structure. Files are placed into directories (folders in Windows) or subdirectories at the desired location in the tree structure.

The file system specifies the rules for naming files. These rules include the maximum number of characters in a filename, what kinds of characters can be used, and how long a filename suffix can be on some systems. File systems also include formats for specifying paths to find files through a directory structure.

The file system is part of the software system. Its existence allows applications to conveniently use abstract named data objects and variable-sized spaces.
