File Systems

IT Infrastructure and Networking

A file system is the method an operating system uses to organize, store, and retrieve data on storage devices, defining structures like directories, metadata, and permissions (examples include NTFS, ext4, and APFS). Systems administrators and software engineers need to understand file systems for tasks like disk partitioning, performance tuning, data recovery, and building software that interacts efficiently with storage. Different file systems offer trade-offs in speed, reliability, and support for features like journaling or encryption.
