How do I make Windows jump to the "directory" field in the Open File dialog?

Question

How can one change the default focus for the open file dialog (Ctrl-O) thus that it directly jumps into the directory text field and not into the file name field?

In its default behavior it always focuses on file name, but this costs time.

Is this just a problem in Windows or does every OS behave like this?
