Yes, see the documentation of `org-confirm-babel-evaluate'. So the
function posted in your previous email could be changed to something
like...
(setf org-confirm-babel-evaluate
(lambda (&rest args)
(let* ((info (org-babel-get-src-block-info))
(result-file (cdr (assoc :file (nth 2 info))))
(duplicat-file-p
(save-excursion
(goto-char 0)
(re-search-forward (concat ":file +" result-file) nil t)
(re-search-forward (concat ":file +" result-file) nil t)))))
(if duplicate-file-p
(prog1 t (message "duplicate result file"))
nil)))
