title: Filter out path strings beginning with strings
body: <p>I have a collection of paths (e.g. <code>C:\Users</code>, <code>C:\Users\cheese</code>, <code>D:\Shadow\stuff</code> ,<code>D:\Shadow</code>). Is there any way to get rid of strings that are lesser path? e.g. to only leave <code>C:\Users\cheese</code> and <code>D:\Shadow\stuff</code> and make it FAST and memory un-intensive?</p>
  
  <p>It is important that the strings can come in any order.</p>
