This feature, along with Portal Pages, Channels, and non-SAIL interfaces, has been deprecated and will be removed in a future release of Appian.
Appian recommends that customers plan migrations of Portal applications to Sites, Tempo, and Embedded interfaces.
See Support for Application Portal and non-SAIL forms for more information.
Files can be uploaded with the file upload component and managed with Appian's Folder and Document Management system.
For information about the Upload Document Smart Service [Deprecated], see the Appian 16.2 documentation.
