title: recursive renaming file names + folder names with a batch file
body: <p>I like to create a batch file (winxp cmd) that recursively goes through a chose folder and sub folders and renames there files+folders with the following rules:</p>
  
  <p>from all file + folder names, all uppercase+lowercase "V" and "W" letters need to be replaced with letters "Y" and "Z".  </p>
  
  <p>e.g.  11V0W must become 11Y0Z.</p>
  
  <p>I believe its possible with FOR /R  but how?
  I think there needs to be a subroutine to be called that checks each letter one by one in addition to basic recursion with FOR /R.   </p>
