title: Create sub folders in My Pictures from Windows Store application
body: <p>I'm trying to create a folder structure within My Pictures folder from a Windows store app. But I can't seem to get pass the first level.</p>
  
  <p>I create my first level folder using the following code:</p>
  
  <pre><code>IAsyncOperation&lt;StorageFolder&gt; appFolder = Windows.Storage.KnownFolders.PicturesLibrary.GetFolderAsync("AppPhotos");
  
  if (appFolder==null)
  {
      //Create folder
      appFolder = Windows.Storage.KnownFolders.PicturesLibrary.CreateFolderAsync("AppPhotos");
  }
  </code></pre>
  
  <p>Now I want to create another folder below this call Level1.</p>
  
  <p>I was expecting to be able to do the following:</p>
  
  <pre><code>appFolder.CreateFolderAsync("Level1");
  </code></pre>
  
  <p>But I don't have a CreateFolderAsync method from my appFolder.</p>
  
  <p>So, how can I create that Folder and then how would I then select it?</p>
  
  <p>Thanks in advance</p>
  
  <p>I'm using Visual Studio 2012, C#4.5, XAML and I'm writing a windows store app.</p>
