title: Detecting the last folder from a list
body: <p>I have several files, thing is that i need to know which one was the last created according to the numbers I give them automatically.</p>
  
  <p>For example if i have: file1, file2, file3 I want to receive the file3. I can't do this with "last modified" because I have other folders and files in the same directory.</p>
  
  <p>Also to this last file I would like to increment his number in 1.</p>
