UTIs have no connection to creator codes. A UTI is defined in terms of: a) filename extension b) HFS type code c) MIME type A UTI _cannot_ be attached to a file as metadata, and a UTI cannot be determined by the system by examining the file's contents. If a file has no filename extension and no HFS type, then no creator code will help you, custom importer or not. Gerriet, could you give your files an HFS type of 'TEXT'? If not, give them a unique HFS type and make your own UTI declaration. -- ____________________________________________________________ Sean McBride, B.
