title: converting filenames to lower case
body: <p>was hoping for some advice as to how to convert existing file names in a folder...all to lower case.</p>
  
  <p>I felt that a good start would be to save the file names in a list and convert them all to lower.</p>
  
  <p>How can I replace the existing file names in the folder to the lower case ones?</p>
  
  <pre><code>List&lt;string&gt; codes = new List&lt;string&gt;();
  string[]productCodes = Directory.GetFiles(@"C:\Users\Ariang\Desktop\screenshotslowercase\screenshots");         
  
  codes = productCodes.ToList();
  codes = codes.ConvertAll(t =&gt; t.ToLower());
  </code></pre>
