HFS+ (Hierarchical File System Plus)

HFS+ (Hierarchical File System Plus) is a file system developed by Apple for organizing and managing files on its macOS and older OS X operating systems. It allows the computer to store, retrieve, and organize data efficiently. HFS+ supports features like hard links, journaling (which helps prevent data loss), and access control lists (for permissions). It is structured in a hierarchical manner, similar to a directory tree, making it easy for users to navigate their files and folders. HFS+ was largely replaced by APFS (Apple File System) but is still relevant for compatibility with older systems and devices.
