Since this information is accessed frequently, for performance reasons it should be recorded in the ExtendedAttributes field of the FileEntry. The MacFinderInfo extended attribute shall be stored as an Implementation Use Extended Attribute whose ImplementationIdentifier shall be set to: "*UDF Mac FinderInfo" The ImplementationUse area for this extended attribute shall be structured as follows: MacFinderInfo format for a directory RBP Length Name Contents 0 2 Header Checksum Uint16 2 2 Reserved for padding Uint16 = 0 4 4 Parent Directory ID Uint32 8 16 Directory Information UDFDInfo 24 16 Directory Extended Information UDFDXInfo MacFinderInfo format for a file RBP Length Name Contents 0 2 Header Checksum Uint16 2 2 Reserved for padding Uint16 = 0 4 4 Parent Directory ID Uint32 8 16 File Information UDFFInfo 24 16 File Extended Information UDFFXInfo 40 4 Resource Fork Data Length Uint32 44 4 Resource Fork Allocated Length Uint32 The MacFinderInfo extended attribute shall be recorded as an extended attribute of every file and directory within the Logical Volume. UDF 2.01 81 March50 April
The following structures used within the MacFinderInfo structure are listed below for clarity. For complete information on these structures refer to the Macintosh books called “Inside Macintosh”. The volume and page number listed with each structure correspond to a specific “Inside Macintosh” volume and page.
