Capture the filename - FTP

We have an internal system which will be sending an xml file utilizing wM ftp port that was configured. Basically, it’s going to execute a flow service once the internal system put it in the designated folder. I would like to capture the name of that xml file? Does anyone have any sugggestion how to accomplish this?

There is an event that gets sent when the put is complete. Create a trigger that waits for “pub.client.ftp:putCompletedNotification”.
