Enter the four-character type field in the
Mac file creator header.
The Macintosh file system is much more advanced than the DOS/Windows file system.
The Operating System (OS) uses the file extension (e.g. .TXT, .DOC.) to associate an application. The Macintosh OS
stores some extra information (attributes) in the data file. There is an attribute called TYPE/CREATOR (4 bytes each)
that is used to combine an 8-byte string calling for Finder INFO. This is used by the OS to determine the correct
application to open the data file.
For Macintosh users, you can also define the MAC Finder (Type and Creator) values. Notice that the Type and Creator
values are case sensitive. If you see "----" in the
Mac file type and/or
Mac file creator
field, it means that these two values are not used.
