Assuming this is C# Winforms, and the PHP reference is spurious...

The first thing you need to do is detect the change: FileSystemWatcher class[^] - but do also read this pretty carefully: FileSystemWatcher - Pure Chaos (Part 1 of 2)[^]
Then it's relatively simple: File.Copy within a try...catch block in case the file is busy, with a retry if it is.
