John,

What I was trying to do is find files that are scattered all over my
hard drive that contain similar two words in them like bar and foo 
and move them to one desired location removing from where they were
originally.  The did not work as desired were attempts when it would
attempt to read and write to the same location.so i would get an error
saying that source and destination were  the same.
