title: Writing txt files to external flash Universal Windows/Windows IoT
body: <p>As mentioned in other posts it is only possible to write pictures, videos and music to an external flash with Windows Devices (In my case a Raspberry Pi 3 B using Windows IoT).</p>
  
  <p>Thankfull to <a href="https://stackoverflow.com/questions/38859872/writing-files-to-external-flash-drive-in-windows-universal">this post</a> I am able to write my data to a jpg. <a href="https://stackoverflow.com/users/6697498/mike-leonardi">Mike Leonhardi</a> wrote that he was able to write also a txt file by modifying the capabilities.</p>
  
  <p>Can someone tell me which modifications have to be done?</p>
  
  <p>Thank you very much!</p>
