OSDarwin, Linux, Microsoft Windows through Boot Camp4IFS driversHFS Plus or HFS is a file system developed by Apple Inc. It served as the primary file system of mac. OS. HFS was developed to replace the Hierarchical File System HFS as the primary file system used in Macintosh computers or other systems running the classic Mac OS. It is also one of the formats used by the i. Pod digital music player. HFS Plus is also referred to as Mac OS Extended or HFS Extended, where its predecessor, HFS, is also referred to as Mac OS Standard or HFS Standard. During development, Apple referred to this file system with the codename Sequoia. At WWDC 2. Apple announced mac. OS High Sierra, in which the default file system of Mac is changed to APFS. HFS Plus is an improved version of HFS, supporting much larger files block addresses are 3. Unicode instead of Mac OS Roman or any of several other character sets for naming items. Like HFS, HFS Plus uses B trees to store most volume metadata, but unlike most other file systems, HFS Plus supports hard links to directories. HFS Plus permits filenames up to 2. NTFS, though until 2. HFS Plus also uses a full 3. HFSs 1. 6 bits, significantly improving space utilization with large disks. HistoryeditHFS was introduced with the January 1. Mac OS 8. 1. 2With the release of the Mac OS X 1. November 1. 1, 2. Apple added optional journaling features to HFS Plus for improved data reliability. These features were accessible through the GUI, using the Disk Utility application, in Mac OS X Server, but only accessible through the command line in the standard desktop client. With Mac OS X v. HFS Plus volumes on all Macs were set to be journaled by default. Within the system, an HFS Plus volume with a journal is identified as HFSJ. Mac OS X 1. 0. 3 also introduced another version of HFS Plus called HFSX. HFSX volumes are almost identical to HFS Plus volumes, except that they are never surrounded by the HFS Wrapper that is typical of HFS Plus volumes and they optionally support case sensitivity for file and folder names. HFSX volumes can be recognized by two entries in the Volume Header, a value of HX in the signature field and 5 in the version field. Mac OS X 1. Apples adoption of Unicode 3. Unicode 2. 1 decomposition used previously. This change caused problems for developers writing software for Mac OS X. With Mac OS X 1. Apple added support for Inline Attribute Data records, something that had been a part of the Mac OS X implementation of HFS Plus since at least 1. Until the release of Mac OS X Server 1. HFS Plus supported only the standard UNIX file system permissions however, 1. Microsoft. Windows XP and Windows Server 2. In Mac OS X Leopard 1. Time Machine. In Mac OS X Snow Leopard 1. HFS compression was added. In open source and some other areas this is referred to as Apple. FSCompression. Compressed data may be stored in either an extended attribute or the resource fork. When using non Apple APIs, Apple. FSCompression is not always completely transparent. In Mac OS X Lion 1. File. Vault 2 was added to the operating system. This addition to the operating system in no way changed the logical structure of the file system. Apples logical volume manager is known as Core Storage and its encryption at the volume level can apply to file systems other than HFS Plus. With appropriate hardware, both encryption and decryption should be transparent. HFS Plus volumes are divided into sectors called logical blocks in HFS, that are usually 5. These sectors are then grouped together into allocation blocks which can contain one or more sectors the number of allocation blocks depends on the total size of the volume. HFS Plus uses a larger value to address allocation blocks than HFS, 3. HFS. 2 When disks were small, this was of little consequence, but as larger capacity drives became available, it meant that the smallest amount of space that any file could occupy a single allocation block became excessively large, wasting significant amounts of space. For example, on a 1 GB disk, the allocation block size under HFS is 1. KB, so even a 1 byte file would take up 1. KB of disk space. HFS Pluss system greatly improves space utilization on larger disks as a result. Nikon D3200 Serial Number Location there. File and folder names in HFS Plus are also character encoded in UTF 1. Unicode Normalization Form D NFD1. HFS filename and therefore count as two code units1. UTF 1. 6 implies that characters from outside the Basic Multilingual Plane also count as two code units in an HFS filename. HFS Plus permits filenames up to 2. UTF 1. 6 code units in length. Formerly, HFS Plus volumes were embedded inside an HFS standard filesystem. This was phased out by the Tiger transition to Intel Macs, where the HFS Plus filesystem was not embedded inside a wrapper. The wrapper had been designed for two purposes it allowed Macintosh computers without HFS Plus support in their ROM to boot HFS Plus volumes and it also was designed to help users transition to HFS Plus by including a minimal HFS volume with a read only file called Wherehaveallmyfilesgone, explaining to users with versions of Mac OS 8. HFS Plus, that the volume requires a system with HFS Plus support. The original HFS volume contains a signature and an offset to the embedded HFS Plus volume within its volume header. All allocation blocks in the HFS volume which contain the embedded volume are mapped out of the HFS allocation file as bad blocks. Notable among filesystems used for Unix systems, HFS Plus does not support sparse files. There are nine structures that make up a typical HFS Plus volume 2Sectors 0 and 1 of the volume are HFS boot blocks. These are identical to the boot blocks in an HFS volume. They are part of the HFS wrapper. Sector 2 contains the Volume Header equivalent to the Master Directory Block in an HFS volume. The Volume Header stores a wide variety of data about the volume itself, for example the size of allocation blocks, a timestamp that indicates when the volume was created or the location of other volume structures such as the Catalog File or Extent Overflow File. The Volume Header is always located in the same place.
