DISCUSSION

On the Mac OS, a file type is a 4-byte character constant that identifies the type of file to the Finder (for example, 'TEXT' for a text file, or 'APPL' for an application). A creator is a 4-byte character constant that the Finder uses to identify the application that created a document; doing so allows the Finder to launch or activate the appropriate application when the document is opened.
