file system

This term refers to the logical architecture that governs how a storage device organizes files. It is a technical term used primarily in computer science and information technology to describe the mapping between physical sectors on a disk and the logical files seen by the user.

In a professional context, it is often used to discuss compatibility and performance, such as when choosing between FAT32, NTFS, or APFS. It is distinct from a "filing system," which typically refers to a physical method of organizing paper documents in folders or cabinets.
