title: Command or Script to rename multiple files in windows
body: <p>I have around 400 movies on my hard-disk, but names of those movies contains dots or underscore in between like "wrong_turn.mkv" or "wrong.turn.mkv". I just want to remove these dots or special characters from the file name and keep the extension as it as.
  Any Command Line command or Powershell/Python or any other script for windows? Thanks.</p>
