As I said in my second post, the issue here is unknown extensions and local files.
On unix, mailcap and mime.types files are provided. On windows, all the extensions are in the registry mapped to mime types. On OS/2, we have no mechanism for mapping extensions to mime types (which is sometimes necessary). Mapping multiple extensions to one mime type is very easy. Since the file is indexed by extension, we can have any extension map to any mime type. There is no need for a mime type to extension mapping. Mike
