title: Android Internal Storage when updating application
body: <p>I use the internal storage (http://developer.android.com/guide/topics/data/data-storage.html#filesInternal) to store some necessary application files, that the user creates.</p>
  
  <p>I suppose that these files are stored forever right? They are removed only when the user uninstalls the application, am I correct?</p>
  
  <p>In case of updating the application (for example from version 1.0 to 1.1) through the Android Market, then what will happen to the files that were stored from the previous version? Are they deleted or not?</p>
  
  <p>Thank you in advance.</p>
