[O] org-export and open odt files always opened in emacs

[Amos Bird]

Greetings!

I'm trying to export and open odt files outside emacs. I've set

  (setq org-file-apps
        `(("\\.org$" . emacs)
          ("\\.cpp$" . emacs)
          (t . ,(cond (IS-MAC "open -R \"%s\"")
                      (IS-LINUX "xdg-open \"%s\"")))))

However exported files are still opened inside emacs. What can I do?

regards,
Amos
