title: GitHub for Mac - Adding Files
body: <p>My commit generates the following error:</p>
  
  <pre><code># Untracked files:
  #   (use "git add &lt;file&gt;..." to include in what will be committed)
  #
  #   "Icon\r"
  no changes added to commit (use "git add" and/or "git commit -a")
  </code></pre>
  
  <p>I am unable to locate Icon\r and typing "git add Icon\r" into Terminal is unsuccessful.  Why is this happening?  Is there a way to add this file to source control from within the GitHub for Mac GUI?</p>
