Does that sound right to you? Ah. I don't think Nautilus has a GUI for this. You can do it manually though, using the XDG MIME types system. If you like reading specifications: http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec If you'd rather have the quick-and-easy version: Create the folder .local/share/mime/packages in your home folder. Create a file in that folder with a .xml extension. Call it "mymimetypes.xml" or whatever you like. Here's one I just made to register a MIME type for Mallard page files: <?xml version="1.0" encoding="UTF-8"?> <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info"> <mime-type type="text/x-mallard-page+xml"> <comment>Mallard Page File</comment> <glob pattern="*.page"/> </mime-type> </mime-info> Change the type attribute to the MIME type you want. Change the comment to whatever you want to see files of that type called in Nautilus. Change the glob pattern to match the extension of the files. You can have multiple glob elements for each MIME type to use that type for any of the globs. You can add more mime-type elements to mime-info to register more types. Save the file, and run the following at the command line: update-mime-database ~/.local/share/mime Nautilus should pick up the changes immediately. -- Shaun _______________________________________________ gnome-list mailing list gnome-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gnome-list
