In the operating system, the main function of file management is to achieve file access by name.

File management is an important function in the operating system. Its importance lies in the fact that in modern computer systems, the user's programs and data, the operating system's own programs and data, and even various input and output devices all appear in the form of files. It can be said that although files can be stored in a variety of media, such as hard disks, floppy disks, optical disks, flash memory, memory sticks, network disks, etc., they all appear in the form of files in front of operating system administrators and users.

File management is one of the five major functions of the operating system, which mainly involves the logical and physical organization of files, the structure and management of directories. The so-called file management is a general term for a set of software in the operating system that implements unified management of files, the files being managed, and some data structures required for file management (it is the organization in the operating system responsible for accessing and managing file information).

From a system perspective, the file system organizes, allocates and recycles the storage space of file storage, and is responsible for the storage, retrieval, sharing and protection of files. From a user's perspective, the file system mainly implements "access and storage by name". Users of the file system can access the information in the files as long as they know the file names of the required files, without knowing where these files are stored.
