Smarter “Confirm File Replace” dialog on Windows

Question

In Windows (XP at least), when you drag a file to a folder that already has a file with the same name, you get a dialog like this:

Does anyone know of a replacement for that dialog that adds a Compare button (preferably configurable to use the comparison tool of my choice)?

Answer 1

Unless you have a windows shell replacement you can't replace this as it is part of the windows shell. This is called by an API and you can't supplement it.
