In a Microsoft-centric workplace, I use task attachments heavily to store emails, design documents, and the like. Especially with email attachments, I'll usually open up the task's attachment folder (C-c C-a f) and simply drag the relevant emails to the folder (which conveniently also copies all of its attachments :)).

Since Org isn't the one adding attachments, the ATTACH tag is often missing. As I move around attachments and tasks, I'll also move their attachments appropriately, sometimes emptying the folder. This causes ATTACH to become a false-positive.

Is there any way I can synchronize the presence of the ATTACH tag with the presence of actual attachments? As an added bonus, can I also update the :Attachments: property with the appropriate file list? (It helps with searching.)

    There's a function org-attach-sync that sounds like it would do what you want. I get an error when I try it. It seems to expect your attachments to be in a git repository. – erikstokes Apr 13 '15 at 1:49
  • @erikstokes Now why on earth would someone make that assumption? :( I'll look into the function, thanks. – Sean Allred Apr 13 '15 at 2:15

There is a function org-attach-sync that claims to do this, but it seems to be expecting you to keep your attachments in a git repository, which you may not be doing (I don't).

So, here's a function that uses org-attach-file-list to look at the list of attachments and change things appropriately. The :ATTACH: tag will be toggled and the Attachments property will be updated or deleted.

(defun org-sync-attachments ()
  "Update the current entry's attachment metadata."
  (interactive)
  (let* ((attachments (if (org-attach-dir)
                         (org-attach-file-list (org-attach-dir)))
                     )
        (tag-state (if attachments 'on 'off)))

    (if attachments 
        (org-set-property org-attach-file-list-property
                          (mapconcat #'url-encode-url
                                     attachments " "))
      (org-delete-property org-attach-file-list-property))
    (org-toggle-tag org-attach-auto-tag tag-state)
    ))

  • To sync all items in a buffer, it's a simple (defun org-sync-attachments-all () (interactive) (save-excursion (goto-char 0) (while (search-forward-regexp "^\\*" nil t) (*-org-sync-attachments)))) – Sean Allred Apr 13 '15 at 15:02

    and a small note -- if your attachments have spaces in the file name, it's better to use #'url-encode-url instead of '#identity. – Sean Allred Apr 13 '15 at 15:08
  • @SeanAllred Good catch on the file names with spaces. That would have bitten me eventually. – erikstokes Apr 13 '15 at 20:55
