There is no "COPY.EXE" on your Windows system, so you can't evoke it this way. COPY is a built-in command of CMD.EXE or COMMAND.COM, depending on what flavor of windows is running.
You'd need to do something like (system cmd /c "copy f1.txt f2.txt"). See the Java Programmer's FAQ, section 18, question 10, at http://www.afu.com/javafaq.html .
