HFS Plus or HFS+ is a file system developed by Apple to replace the Hierarchical File System (HFS) as the primary file system used in Macs.

HFS Plus or HFS+ is a file system developed by Apple to replace the Hierarchical File System (HFS) as the primary file system used in Macs. HFS Plus is also referred to as Mac OS Extended (or, erroneously, “HFS Extended”), where its predecessor, HFS, is also referred to as Mac OS Standard (or, erroneously, as “HFS Standard”).

HFS+ supports much larger files than HFS (block addresses are 32-bit length instead of 16-bit) and uses Unicode (UTF-16 encoding) to name files, folders, and other filesystem objects. HFS+ also permits filenames up to 255 UTF-16 characters in length, and n-forked files similar to NTFS.

Apple has continued active development of HFS+: it has been the default filesystem of all OS X Macs. Features added over time include journaling, folder hard-linking, compression, and encryption.

In python on OSX with HFS+ how can I get the correct case of an existing filename?

I am storing data about files that exist on a OSX HFS+ filesystem. I later want to iterate over the stored data and figure out if each file still exists. For my purposes, I care about filename case sensitivity, so if the case of a filename has…

How to convert path to Mac OS X path, the almost-NFD normal form?

Macs normally operate on the HFS+ file system which normalizes paths. That is, if you save a file with accented é in it (u'\xe9') for example, and then do a os.listdir you will see that the filename got converted to u'e\u0301'. This is normal…

In Windows, I can use the FindNextChangeNotification API to watch a file or folder for changes. For example, I can watch a folder and get notified when a file is added or removed. Is there a similar API on OS X?

What are the APIs for working with HFS+ named forks?

I know that resource forks are deprecated in Mac OS X. It's not clear whether the less well known and little used named forks are also deprecated. HFS+ actually supports an arbitrary number of arbitrary length forks for any file. (Mac's named forks…
