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.
