Thanks for the tip. That probably is a better way to do it. I thought about memory cost wasn't an issue, since the launch program ran on a dedicated box.

>I used that method with good results for many years, Mike, till someone pointed out that keeping the VFP app "alive" while it waits for the timer to fire has a memory cost, and the Windows Scheduler can fire the VFP app at set intervals at no memory cost at all when the app is dormant.

>>>I have done this using a simple all-VFP solution. The form program includes a timer. Every time the timer fires it checks the target directory for target file(s).
