title: mkDir(s) vs Files.createDirectory(ies)
body: <p>What is the difference between <code>file.mkDir()</code> and <code>Files.createDirectory(path)</code>.
  Is there any cases which suites better for any of them? Or <code>Files.createDirectory(path)</code> is just newer version of <code>file.mkDir()</code> (from newer Java version?</p>
  
  <p>Thanks in advance.</p>
