Do you really mean is it a program? - ie an executable file? Or do you 
just want to know if the file (any kind of file) exists?

There are ways to do what you want but you need to be much more specific.

You need a loop. It will look something like(pseudo code)

while True:
    you existing copy code here
    ask the user if they want to do more
    if they don't:
       break  # exit the loop
