title: Copy files from nested directories to similar nested directories
body: <p>I have files under nested directories like 
  /x/0/0/0/a.txt till /x/9/9/9/a.txt
  To be more specific
  Under /x/ there are 0-9 folders 
  Under /x/0/ there are 0-9 folders 
  Under /x/0/0/ there are 0-9 folders 
  Under/x/0/0/0/ there are files like a b c. </p>
  
  <p>Now all these files needed to be copied to a directory like
  /y/ , where the previous directory structure should be followed. </p>
