WWW file:// protocol to list a directory

Hi !

Is WWW supporting directory listing with file:// protocol?

I've made a simple function :

 public static IEnumerator LoadText(
     string uri, 
     Action<bool, string> onLoad, 
     Action<float> onFrame = null
 )
 {
     if (OnLoad == null)
         throw new NullReferenceException("onLoad");

     WWW www = new WWW(uri);
 
     while (!www.isDone)
     {
         if (onFrame != null)
             onFrame(www.progress);
         yield return null;
     }
 
     if (onFrame != null)
         onFrame(www.progress);
 
     if (!string.IsNullOrEmpty(www.error))
     {
         onLoad(true, www.error);
     }
     else
     {
         onLoad(false, www.text);
     }
 }

I would like to use it to download (text) files and list distant shared directories :

 void Awake()
 {
     // string uri = "file://127.0.0.1/C://path/to/my/file.txt";   // Works
     // string uri = "file://127.0.0.1/C://path/to/my/directory";  // Doesn't work
     // string uri = "file://127.0.0.1/C://path/to/my/directory/"; // Doesn't work
     // string uri = "file:///C://path/to/my/directory/";          // Doesn't work
        string uri = "file:///C://path/to/my/directory";           // Doesn't work

     StartCoroutine(LoadText(uri, (error, text) =>
     {
         if (error)
             Debug.LogError("Download failed: " + text);
         else
             Debug.Log("Text: " + text);
     }, (progress) =>
     {
         Debug.Log("Progress: " + (progress * 100).ToString("F2") + "%");
     }));
 }

Is there someting I'm missing, or directory listing is not supported? I would like to get something like this:
