Kathy,
You could use the fileset-ftp protocol to perform the ftp for you, and depending on what version of Cloverleaf you are running, utilize the ‘Advanced Scheduling’ option (I think there are some known issues with the “Advanced Scheduling” option prior to 5.3, but you can check with Support on that). In lieu of the ‘Advanced Scheduler’ option, you could set a an entry in cron to start/stop the thread at the desired times or you could also control the start/stop of the thread via an Alert (with an ‘exec’ action) using the “Time Window” functions there. Just some other ways to “skin a cat”.

P.S. Just remember that the fileset-ftp protocol will delete the sourcefile after it processes it (unless you tell it to do otherwise with a ‘Deletion’ tps)
