file system

(operating system)
(FS, or "filesystem") 1. A system for organizing directories and files, generally in terms of how it is implemented in the disk operating system. E.g., "The Macintosh file system is just dandy as long as you don't have to interface it with any other file systems".

2. The collection of files and directories stored on a given drive (floppy drive, hard drive, disk partition, logical drive, RAM drive, etc.). E.g., "mount attaches a named file system to the file system hierarchy at the pathname location directory [...]" -- Unix manual page for "mount(8)".

As an extension of this sense, "file system" is sometimes used to refer to the representatation of the file system's organisation (e.g. its file allocation table) as opposed the actual content of the files in the file system.

Unix manual page: fs(5), mount(8).

file system

(1) For copying, moving, renaming and deleting files, see file manager.

(2) The software and method for storing and retrieving files on a disk, SSD or USB drive. A file system is a major component of the operating system (OS). Applications command the OS to input and output data, and the file system reads and writes the sectors on the storage drive.

The file system manages the folder/directory structure and provides an index to the files. It also defines the syntax used for the "path" to the files. File systems dictate how files are named as well as the maximum size of each file and the total storage capacity it can handle. See path and long file names.

There are numerous file systems in use; for example, Windows uses FAT32, exFAT and NTFS, while Macs use FAT32, exFAT, HFS+ and APFS. Linux uses ext2, ext3, FAT32 and exFAT. Unix systems use UFS, ext2, ext3 and ZFS. See journaling file system, hierarchical file system, block level, cluster, FAT32, NTFS, APFS, HFS, NFS, UFS, ext and ZFS.

File System Interaction
When the application sends a request to the operating system to store data to or retrieve data from storage, the file system is the software that actually locates and reads or writes the data.

One Drive, Two File Systems
This external Lacie hard drive connected to a Mac is partitioned into two drives, each with its own file system. ExFAT allows the drive to be read and written on a Windows PC as well, while Mac OS Extended is another name for the Mac's HFS+ file system.
