You could also use the /ALLOW_SAME keyword to FILE_COPY. --Wayne

Attempting to copy a file on top of itself by specifying the same file for SourcePath and DestPath is usually considered to be an error. If the ALLOW_SAME keyword is set, no copying is done and the operation is considered successful.
