Hi,

instead of overriding OnbackKeyPress you have to register the event
...
Windows.Phone.UI.Input.HardwareButtons.BackPressed += HardwareButtons_BackPressed;
...

void HardwareButtons_BackPressed(object sender, Windows.Phone.UI.Input.BackPressedEventArgs e)
{
// your code
e.Handled = true; // if you wanna prevent that the "standard"-eventhandler is called and your app getting closed
}

Best,

Thanks.
And what about isolated storage?
I can't use them any more and power tools ran out

    Look for StorageFile and StorageFolder:

    And here is a Storage Helper class from Jerry Nixon that is useful: http://codepaste.net/gtu5mq
