AppleSingle and AppleDouble format internals.
AppleSingle/AppleDouble Developer’s Note - Version 2.
The Finder's "Archive as." functionality puts them in subdirectories named _MACOSX.ĪppleDouble header files begin with signature bytes (hex) 00 05 16 07. Sometimes, instead of using a different filename, the header files are put in special subdirectories named ".AppleDouble". This avoids corrupted records containing partial old and partial new data. Instead of overwriting existing metadata records in place, it writes entirely new records, points to the new ones and then releases the old ones, an approach known as redirect-on-write. Read on for useful information on M4V files. One of The Unarchiver's options is to use an extension of ".rsrc". Apple File System is designed to avoid metadata corruption caused by system crashes. You no doubt have used M4V files without asking the fundamental question: what is M4V You also need to know which player can play such files. However, in the OS X era, the convention is to prefix the header filename with "._" (a dot and an underscore). The specification says that the header filename should be prefixed with a "%", or prefixed with "R.", or have a file extension of ".ADF", depending on the filesystem's capabilities. The AppleDouble format keeps the data fork of the file in its original format and filename (this is the main file, as used by non-Mac operating systems, and for many file formats, the only one that matters), and creates a second "header" file with the resource fork as well as Finder metadata.
