Using Watched Folders in AEM Forms

An administrator can configure a network folder, known as a Watched Folder, so that when a user places a file (such as a PDF file) in the Watched Folder a pre-configured workflow, service, or script operation is started to process the added file. After the service performs the specified operation, it saves the result file in a specified output folder. For more information about workflow, service, and script.
