Thanks!.

Yeah, docstring is usually the last I add, since I should at least know what the function is supposed to do ;-)

What is the use of (and org-attach-allow-inheritance t)? Doesn't it always returns org-attach-allow-inheritance?
Anyways, I'm not really sure if I understand the doc of org-entry-get correctly. Does org-entry-get not automatically
take inheritance into account, based on the the per-entry or global setting?

Yes, of course.

Why that? Aren't old and new holding the appropriate dirs in that case and copy over / delete as they should?

Ok. I wasn't aware of the difference, since I have (fset 'yes-or-no-p 'y-or-n-p) in my .emacs.

I took it from org-attach-delete-all. But you're delete-directory is probably better than a shell-command.

Latest version:

(defun flo/org-attach-move (&optional arg)
  "Move current attachements to another directory.
  When ARG is non-nil, reset attach directory.  Create directory if
  needed."
  (interactive "P")
  (let ((old (org-attach-dir))
        (new
         (progn
           (if arg (org-entry-delete nil "ATTACH_DIR")
             (let ((dir (read-directory-name
                         "Attachment directory: "
                         (org-entry-get nil
                                        "ATTACH_DIR"
                                        (and org-attach-allow-inheritance t)))))
               (org-entry-put nil "ATTACH_DIR" dir)))
           (org-attach-dir t))))
    (unless (or (string= old new)
                (not old))
      ;; FIXME: Need a special case for directory reset (non-nil ARG).
      (when (yes-or-no-p "Copy over attachments from old directory? ")
        (copy-directory old new t nil t))
      (when (yes-or-no-p (concat "Delete " old))
        (delete-directory old t)))))
