title: Touch file to update the date/time of file? (Modified Date) (WindowsXP BatchScript)
body: <p>What's a batch script command to touch on a file to update its date and time to the current date and time? (Modified Date)</p>
  
  <p>For example, Joe Blow sends me a text document which he created months ago, when he emails me the document, I want to keep track of how old it is from the day I received it (not when he created it) so I want to update the file's date/time to the current date/time.</p>
  
  <p>I have a batch script to automatically weed out files that haven't been edited within 90 days, so this is troublesome when I receive a particularly older file then all of a sudden it disappears.</p>
  
  <p>And I need it via a batch script as I have hundreds of files to manage, and it's for archiving files.</p>
