David,

I think the point Chris is trying to make is that 'moving' a file is
really just changing the name, in general the operations are the same.

Saying that a.txt is now named b.txt is really the same thing as saying
that /mydir1/a.txt is now named /mydir2/a.txt.

When you 'move' a file it is not actually moved unless you move it from
one drive (whether physical or logical) to another, you're just changing
the name that it is known by.  This is why 'moving' a file is more or
less instantaneous.

On a side note, if you are moving a file from one drive to another the
operation is not really a 'move', it is first copied to the destination
drive then deleted from the source drive.
