The Ticket Export creates a zip file with a PDF of the ticket, as well as the ticket's attachments, if available. The same report is used to create the export as is used to print from the Tickets application.
In combination with the "Ticket Changed" trigger and the "File System" action, one could, for example, automatically archive all finished tickets to a selected folder.
Note: The PDF is created using the print report and the permissions of the task owner.
