title: Update file or folder Date Modified
body: <p>I need to update the "Date Modified" property of files and folders as they are copied from one location to the other so that "Date Modified" = Current System Time.  I have a PC with Windows 7, and I do NOT have administrative rights on it, so I can't install any custom utilities.  My current bat file uses XCOPY:</p>
  
  <pre><code>xcopy "\\sharepoint\dept\gis\Abandoned_Wire\*.*" "\\corp.dom\fs4\g1\OUTPUT\GRIDPROD\PDF\Maps\Abandon Wire Maps" /c /s /r /y /i
  </code></pre>
  
  <p>On my Windows XP box I use the "touch" command from UnxUtils, but I can't find an equivalent that's native to Windows 7.  Thank you!</p>
