dialog boxes and user interaction always add far more to the codebase than you'd expect! having said that, a silent copy of existing templates to a subfolder would add very little...

Paul, very, very little... We are not talking about coding in 80' Programmers have libraries. Dialog box could be just 1 single object dialog box creation  with parameter like string which should be displayed (like "Should user templates be preserved?"). And ready to go. After interaction (already programmed at library level) it ends with atrrib set to value according to user answer (yes or no) additional call to function which save is performed or skipped. And that's all. Or something like that. Very little additional work, probably about 1 minute coding (cafe included) and 5 minutes for testing.
