I'm using filesystem events to react to a file create/change in similar cases. The only problem is binding to them, but I've written a .NET ActiveX thet does that for me. Use that inside a VFP form and I'm able to write VFP code to react to the events. Another solution I'm also using is a small .NET app that reacts to evnts and writes a message to a message-queue which in its turn is monitored by a VFP application.
