title: Can i get all thumbnails in my specific folder?
body: <p>I want to get a thumbnail image of all photo files in a specific folder.
  (Example: My C: \ Mypic)</p>
  
  <p>I found another way to get a single thumbnail image, but this isn't exactly what i want</p>
  
  <pre><code>async private Task&lt;BitmapImage&gt; Thumbnail_call()
      {
          var files = await KnownFolders.PicturesLibrary.GetFilesAsync();
          var thumb = await files[0].GetThumbnailAsync(Windows.Storage.FileProperties.ThumbnailMode.PicturesView);            
          var bitm = new BitmapImage();
          bitm.SetSource(thumb);
          return bitm;
      }
  </code></pre>
  
  <p>I think that i have to use foreach sentence</p>
  
  <p>Can you give me a solution to this problem?</p>
