Generally you cannot ADD files to an optical disc once you have created one.  To do so you would have had to create it in multi-session mode to begin with which you would have had to set up when you first created it (if k3b can do that).  The only exception is if you used a true RW optical disk (very slow) where you can effectively erase files as well.<br>
