- A file system (filesystem) is a means to organize data expected to be retained after a program terminates by providing procedures to store, retrieve and update data, as well as manage the available space on the device(s) which contain it. A file system organizes data in an efficient manner and is tuned to the specific characteristics of the device. There is usually a tight coupling between the operating system and the file system. Some filesystems provide mechanisms to control access to the data and metadata. Ensuring reliability is a major responsibility of a filesystem. Some filesystems provide a means for multiple programs to update data in the same file at nearly the same time.
Without a filesystem programs would not be able to access data by file name or directory and would need to be able to directly access data regions on a storage device.
File systems are used on data storage devices such as magnetic storage disks or optical discs to maintain the physical location of the computer files. They may provide access to data on a file server by acting as clients for a network protocol (e.g., NFS, SMB, or 9P clients), or they may be virtual and exist only as an access method for virtual data (e.g., procfs). This is distinguished from a directory service and registry.
