title: Delete the first line of a text file without reading it
body: <p>I'm working with a <em>very</em> large text file (around 70 thousand lines) and I want to remove the top line.</p>
  
  <p>Clearly, loading the entire thing into memory, deleting the top line, then re-writing the whole thing again is inefficient:</p>
  
  <pre><code>var lines = File.ReadLines(accountFileLocation.Text).Skip(1);
  File.WriteAllLines("output.txt", lines);
  </code></pre>
  
  <p>Is there any other way to do it?</p>
