Thanks. That partially works, but what is not handled (and is also not handled when using the old-style file types) is the enabling of aliases to files of the appropriate type identifier in the Choose File dialog.
set vFileList to choose file of type {"public.jpeg", "public.tiff"} with prompt vPrompt with multiple selections allowed without invisibles
... works on files having either a file type of "JPEG" or "TIFF" or extension of in the list {"jpg", "jpeg", "tif", "tiff"}, but won't recognize aliases or symlinks to those files.
What I'd like to do is to do the above, plus recognize aliases or symlinks having either a file type of "JPEG" or "TIFF" or extension of in the list {"jpg", "jpeg", "tif", "tiff"}, yet leave other files disabled. Right now, my workaround is not to filter by type at the Choose File stage, and filter out selected files that don't have the right characteristics before operating on them.
