Filesystem

A filesystem is a method and data structure that an operating system uses to control how data is stored and retrieved on a storage device, such as a hard drive or SSD. It organizes files into a hierarchical structure of directories and provides metadata like file names, sizes, and permissions. Common examples include NTFS for Windows, ext4 for Linux, and APFS for macOS.
