title: batch file to delete files filename ending in particular characters
body: <p>I am looking to write a batch file that will remove all files from a directory where there file name ends in a particular number.</p>
  
  <p>Eg delete all files of type .js from a folder where the filename end in 1.1.1.0</p>
  
  <p>Any tips as to how I may write such a batch file to achieve this?</p>
  
  <p>How would it be different if I wanted to delete all of the files of type .js that didn't end in 1.1.1.0?</p>
