:) I'm using the flash drive so I can backup small DBs and have time to monitor it. In the real environment the .bak will be over 200Gb so it's not just nicety to have it show something like progress.

This gets weirder the further I go. Now, I've set a timer to monitor the file creation. The wierd thing is - I know the file size is growing as the backup runs. If I start Windoze Exploder and navigate to the file, when I click on the file, my VFP exe shows the new size. Explorer doesn't! Navigate to another file and back, same thing. Hit F5 in Explorer, the file size changes and so does my VFP exe.

So first question. Is there a way to make VFP force Windows to "refresh" itself?

Second question Does anybody understand C++ code? I've got a sample called mprocess.cpp which comes with SQL Server. It uses the SQL Server Virtual Device Interface which looks promising, but I never did C++!
