title: Best way to copy or move files with Objective-C?
body: <p>I was wondering, is there a best practice to write an OSX programm that copies or moves a file from one place to another? </p>
  
  <ul>
  <li>is there some NSSomething method I can call?</li>
  <li>Do I have to work with Input/Output streams?</li>
  <li>Or is the best way maybe to just rely on passing commands to the finder?</li>
  </ul>
  
  <p>Bonus question: How do I get percentages a la "copy 12% complete" with one of these methods?</p>
  
  <p>Thanks for your help!</p>
