Which Trigger Event should you select to watch a directory for files that have been created, modified, or deleted?

• A. Resource or Network Directory (updated)
• B. FME Server System Event (received)
• C. UDP Message (received)
• D. JMS Message (received)

Answer: (A)

Watching a folder for file activity is a task that hinges on a trigger designed to monitor file system changes. The trigger that fires when a directory’s contents are updated—covering creation, modification, and deletion of files—is the one tied to a Resource or Network Directory in an updated state. This type of trigger is specifically built to detect changes in a directory, so it will start the workflow as soon as new files appear, existing files are modified, or files are removed. The other options respond to different kinds of events: system-related notices from the server, or incoming messages over UDP or JMS. They aren’t designed to track changes inside a directory, so they wouldn’t respond to files being created, modified, or deleted.
