 <p><code>git add .</code> will add any files in the current directory and any sub-directories. I would imagine that you could also do <code>git add .\relative\path\to\file</code> as well. If the file still resists, force a change (add a new line somewhere in the file where it won't hurt anything) and try again. Sometimes the diff that git runs doesn't detect that the file has changed.</p>
