The window Freezes!?

[shadow]

When I use CopyFile to copy large files (1Gb), the window of my program freezes while the file is being copied.  How can I prevent this?

This is normal in a single thread application. To solve the problem do the copy in a seperate thread and have it advise the calling thread whn its finished.
