In that case:
#+BEGIN_SRC emacs-lisp
(defun file-description (start end path bracketp)
(put-text-property start end 'display (shell-command-to-string
(format "file %s" path))))
(org-link-set-parameters
"file"
:activate-func 'file-description)
#+END_SRC
With this, you have to have a way to insert links that isn't typing them in
by hand; as soon as emacs recognizes the link, it changes the display which
makes it hard to type.
The shell command puts a long string, so you might replace that with
something that has the output you wanted above.
