With thousands of PC Extension codes



The Type/Creator Database Website



Every Macintosh file has two four-character codes associated with it - its type and creator. The Creator code is unique to each application and enables the Finder to attach documents to their parent applications. This way you can "double click" on the Icon of a document and MacOS will open it with its correct application. The Type code lets this application to differentiate among its files. Type/Creator Database is a collection of those codes.
Apple does not provide such a database, they only allow you to see if a certain code is already registered (A registered code must not actually be in use).

In OS X Apple diverts from the pure Type/Creator scheme, leaning more into the PC/Unix world where file extensions define file typing.
Type/Creator codes are still supported by Apple. Developers that are aware of the benefits of Type/Creator codes keep using them.

File extensions gain importance in the Macintosh world. So Type/Creator Database now supplies PC extension codes. Thousands of
extension codes from free sources over the Internet are now part of TCDB for no extra charge

TCDB 2003.10 for OS X includes 58,921 entries of Type/Creator codes
19,737 entries with PC file extensions
