title: C#: Appending *contents* of one text file to another text file
body: <p>There is probably no other way to do this, but is there a way to append the contents of one text file into another text file, while clearing the first after the move?</p>
  
  <p>The only way I know is to just use a reader and writer, which seems inefficient for large files...</p>
  
  <p>Thanks!</p>
