title: Upload files in Google App Engine
body: <p>I am planning to create a web app that allows users to downgrade their visual studio project files. However, It seems Google App Engine accepts files uploading and flat file storing on the Google Server through <code>db.TextProperty</code> and <code>db.BlobProperty</code>.</p>
  
  <p>I'll be glad anyone can provide code sample (both the client and the server side) on how this can be done.</p>
