Hierarchical File System Plus (HFS+)
Hierarchical File System Plus (HFS+) is a file system developed by Apple Inc. and introduced in 1998 as an enhancement to the original Hierarchical File System (HFS). HFS+ is the primary file system used on Apple's macOS operating system and was designed to address the limitations of its predecessor, including support for larger file sizes, better metadata handling, and improved performance. HFS+ supports features such as file compression, journaling for enhanced data integrity, and extended file attributes. Despite its long-standing presence, HFS+ has been gradually replaced by the Apple File System (APFS), introduced in 2017, which offers superior performance, security, and scalability, particularly for modern storage technologies such as solid-state drives (SSDs) and flash storage.
