If you can think of a way to do it in appian, please comment.</p><div style="clear:both;"></div>https://community.appian.com/thread/124941?ContentTypeID=1Wed, 24 Jan 2024 12:07:32 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:d076ec10-a832-460d-8164-e52b6bba5201Stefan Helzle<p>Uploading large files becomes tricky with Appian.
