title: Deploy WP8 app to device and save all its settings after rebuilding the project
body: <p>I have accidentally killed one of my WP projects in VS2013. I receovered the source code from the backup, but now, if I try to recompile it and deploy to my device for further debugging, all my app data in the app IsolatedStodage area will be wiped (see <a href="https://stackoverflow.com/questions/25362744/all-files-in-isolatedstoragefile-store-disappear-after-rebuilding-wp8-silverligh">this post</a>).</p>
  
  <p>The problem is that I have gathered some important data in my app, and need to save them for later use with newer versions of my app. Is there a way to access the file system on a WP device unlocked for development and save the corresponding IsolatedStorage files for the app? I know that it's possible for the WP8/8.1 emulator (we can mount the .vhd files), but what about a WP device? And if it it's possible, what files/folders do we need to save?</p>
