This class represents the mac os file information dictionary. This is definitively detailed in:.

The ISO PDF Specification, ISO 32000-1:2008 PDF 1.7; Table: 47, page 105.

The MacOS file information dictionary stores classic MacOS file metadata for embedded files: the four-character creator code and file type code used by the classic MacOS Finder.

The Creator entry holds the four-character application creator code. The ResFork entry holds an embedded copy of the file's resource fork as a stream.

These entries are preserved for compatibility with documents created on classic MacOS systems. They have no functional meaning on modern operating systems but allow round-tripping through PDF without losing MacOS-specific metadata.
