- * Notes:
- * DoubleEntryFileDatesInfo
- * File creation, modification, backup, and access times as number of seconds
- * before or after 12:00 AM Jan 1 2000 GMT as SInt32.
- * DoubleEntryFinderInfo
- * 16 bytes of FinderInfo followed by 16 bytes of extended FinderInfo.
- * New FinderInfo should be zero'd out. For a directory, when the Finder
- * encounters an entry with the init'd bit cleared, it will initialize the
- * frView field of the to a value indicating how the contents of the
- * directory should be shown. Recommend to set frView to value of 256.
- * DoubleEntryMacFileInfo
- * This is a 32 bit flag that stores locked (bit 0) and protected (bit 1).
