Sussed it (I knew this would happen. Stare at it for hours then as soon as
you post the question, the answer hits you!)

The initial directory doesn't exist. The first call to 'walk' should have
been: walk("D:\\....").

Top prize for a crap error message, though!

If it had mentioned 'file' or 'directory', I might have found it sooner.
