title: Java Files.walkFileTree with UNC Path
body: <p>I am trying to recursively list a directory under a UNC Path. My code works with regular local directories.</p>
  
  <p>I have tried many uri formats and many API call combinations ie.</p>
  
  <pre><code>    String url = "\\\\xxx.xxx.xx.xxx\\04_TRANSFER\\Edgar\\Folder_Sync_Test";
      String url2 = "file://xxx.xxx.xx.xxx/04_TRANSFER/Edgar/Folder_Sync_Test";
      String url3 = "file:////xxx.xxx.xx.xxx/04_TRANSFER/Edgar/Folder_Sync_Test";
  
      UNCTest test = new UNCTest();
      File f = new File(url);
      System.out.println("============================================");
      try {
          Files.walkFileTree(f.toPath(), test);
      } catch (Exception e) {
          System.out.println(e.getMessage());
      }
      System.out.println("============================================");
      try {
          Files.walkFileTree(Paths.get(URI.create(url2)), test);
      } catch (Exception e) {
          System.out.println(e.getMessage());
      }
      System.out.println("============================================");
      try {
          Files.walkFileTree(Paths.get(URI.create(url3)), test);
      } catch (Exception e) {
          System.out.println(e.getMessage());
      }
  </code></pre>
  
  <p>However all I get are MalformedUrlException(s) or simply \xxx.xxx.xxx.xxx\04_TRANSFER\Edgar\Folder_Sync_Test: Der Netzwerkname wurde nicht gefunden. (Networkname/path path not found).</p>
  
  <p>I am beginning to wonder if it's even possible to do what I want here?</p>
  
  <p>PS. the "test" class here simply extends SimpleFileVisitor</p>
