title: Saving Files c# - without overwriting?
body: <p>I am saving data to a file every 60 secs, I have it saving every 60 secs ok but it deletes the previous data added. Is there a way in which it would add to the file rather than overwrite it. And without using save dialog as it is done in the background. </p>
  
  <p>Any feedback is greatly appreciated</p>
