Just a comment on the SHChangeNotifyRegister API function that the VFP sample uses, from MSDN:

"Note This function is available through Microsoft Windows XP Service Pack 2 (SP2) and Windows Server 2003. It might be altered or unavailable in subsequent versions of Windows."

This was an undocumented API function that MS was forced to document (I do not know the context of when and why, I think it had to do with the EU)

You can bet two things:

1. That the function is not properly documented.
2. That MS will change/remove this function in the future just to piss off and/or f....up every potential competitor that used it.

Myself, I would just go with a timer and check file dates.
