title: How I can find out the available free space in a universal Windows Phone 8.1 App
body: <p>does anyone know how to access the available free space in a universal Windows Phone 8.1 App? In a Windows Phone 8(.1) Silverlight App I could use this Code:</p>
  
  <pre><code>int availableStorage = IsolatedStorageFile.GetUserStoreForApplication().AvailableFreeSpace;
  </code></pre>
  
  <p>But System.IO.IsolatedStorage isn't available in a Windows (Phone) 8.1 App.</p>
