HFS+ is a [[journaling]] filesystem designed by Apple to replace the aging [[HFS]] format. It is also the filesystem used on all iPod devices. It was introduced on January 19th, 1998 in the Mac OS 8.1 update. In the OSX 10.2.2 update, in November 11th, 2002, Apple added journaling to the HFS+ Filesystem. |

HFS+ is the successor of [[HFS]], and was introduced by Apple in Mac OS 8. The main reason is support for larger disks than HFS, but it also has support for journaling and links. The format is described in [http://developer.apple.com/mac/library/technotes/tn/tn1150.html Apple's documentation] |

The filesystem supports much larger block amounts (32 bits), which means that instead of having a maximum of 65,535 files, you can now have 4,294,967,295 (2³²-1) files. The max filesize is now 8 EiB, instead of 2 TiB |
