HFS+ employs UTF-16 to encode files and folders and permits file names up to 255 characters, making it easier to have a descriptive name.Īpple added the journaling feature to HFS+ to improve data reliability in Mac OS X 10.2.2, which soon became the default in Mac OS X 10.3. Maximum size of a file and a volume: 8 EB Maximum number of files in a volume: 2.1 billion This allows more allocation blocks and a smaller block size, which means less space is wasted. HFS+ uses a 32-bit value to address allocation blocks, two times larger than its predecessor HFS (stands for Hierarchical File System). Without file systems like HFS+, saving a file to a drive is like throwing a rock into the sea, impossible to be found. It creates a directory that expands as files are added to the drive and records metadata and file names.

HFS+ is a file system that is significant for making full use of a storage device and how data is retrieved and saved. Startup File: For booting of non-Mac computers What is HFS+ used for?

Volume Header: Store information about the volume, such as creation time and the number of files.Īllocation File (bitmap): Track if an allocation block is used or free.Ĭatalog File: B-tree that describes the folder and file structure on a volume.

HFS+, also referred to as HFS plus, Mac OS Extended or HFS Extended, has been the primary journaling file system of the Mac OS X series since the release of Mac OS 8.1 in 1998. Mac OS X uses the HFS+ format by default and also supports journaling, which makes it easier to recover data in case of a hard drive crash.As the default file system on Mac before APFS, you may see or heard of HFS+ often but wonder what it is and how it differs from other file systems like exFAT and NTFS. This means disk space can be used much more efficiently on large hard disks. HFS+ allows for smaller clusters or block sizes, which reduces the minimum size each file must take up. Since HFS was not originally designed to handle large hard disks, such as the 100GB+ hard disks that are common today, Apple introduced a updated file system called HFS+, or HFS Extended, with the release of Mac OS 8.1. Windows hard drives are typically formatted using WIN32 or NTFS file systems. Since HFS is a Macintosh format, Windows computers cannot recognize HFS-formatted drives. When a hard disk is formatted for a Macintosh computer, the hierarchical file system is used to create a directory that can expand as new files and folders are added to the disk.

Stands for "Hierarchical File System." HFS is the file system used for organizing files on a Macintosh hard disk.
