title: User content Folder Structure based on UserID while hiding total users
body: <p>I'm trying to figure out a <strong>folder structure</strong> for storing user content such as images, which will work for a massive amount of users. I was going to go with something like... <strong>000/000/001</strong>  (user id 1) ....999 max subfolder per folder.</p>
  
  <p>But I would like to <strong>hide the total number of users</strong>, easily seen by starting at 1. Should I start at some random number like 349203480? I'm baffled as to how to work out the folders based on ID this way. Is there some better/easier way?</p>
