If it does, go ahead and pull the file. If it doesn&#39;t exist, email your user. I wouldn&#39;t suggest doing this is the directory has many documents.</p><div style="clear:both;"></div>https://community.appian.com/thread/71643?ContentTypeID=1Mon, 27 Jan 2020 16:58:53 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:f0aaa910-8d4d-4f43-b60d-e877b75954e0normanc<p>See&nbsp;<a href="/discussions/f/process/11643/how-to-handle-the-exception-of-a-node-in-process-and-define-a-different-flow-if-exception-occurs">https://community.appian.com/discussions/f/process/11643/how-to-handle-the-exception-of-a-node-in-process-and-define-a-different-flow-if-exception-occurs</a></p><div style="clear:both;"></div>
