One of the following:
            
            
               
               -  You have tried to COPY a file that you have already started copying.
 
               
               -  You have incorrectly spelled the name of either the file you have previously started to COPY, or the file you currently want
                  to copy.
               
 
               
            
            
            
               
               Resolution:
               
               Revise your program so that the file you have already started to COPY is copied completely before you try to COPY the same
                  file again.
               
               
               Correct the spelling error.
