title: Verifying the size of a subdirectory
body: <p>I want to write a python script that aims to traverse a root directory <code>E:\abc</code> and find whether a subdirectory <code>Test</code> is available in any directories or not. If <code>Test</code> is available and <strong>not empty</strong>, print <code>OK</code> if <code>Test</code> directory is empty, otherwise print <code>NOT_OK</code>. Please help.   </p>
