title: How to obtain file_id from "file name" in Box.com API
body: <p>I am looking to use the Box.com API to download a file. Their API documentation shows that a <code>file_id</code> is required to call the API endpoint. However, I cannot find how to obtain the <code>file_id</code>. How do you obtain the <code>file_id</code> if all you have is the file name? </p>
  
  <p>Along the same lines what if the file is located in a specific directory within the Box.com user's account. Can you obtain the <code>file_id</code> from a given path?</p>
