title: Inaccessible files and File.list()
body: <p>while searching my file system for a file, my program threw a null pointer exception because File.list() could not access 'Documents And Settings' on my file system and an attempt to parse String[] myArray = File.list() when myArray was null threw the exception.</p>
  
  <p>how can I check to see if a file or folder can not be access using File and keep that from happening?</p>
