My program uses a custom file type and I was wondering how to make
sure my extension is unique. On Apple's Data Type Registration page
they only register creator codes. They no longer register file
types. What about file extensions?
I think the best you can do here is use Google and see if there are
any references to your preferred extension out there. I don't think
there is any central repository of file extensions out there, because
there is no way that could be controlled across platforms. But only
Apple operating systems use creator codes, which is why Apple has had
a registry for years.
As for type codes, you can use them however you wish; there are a few
standards, like 'TEXT' and 'PDF ' you should probably avoid with a
proprietary file type, but you probably knew that. Only the creator
code really matters.
