title: Batch file running a command in every subfolder
body: <p>Basic question - Is it possible to create a batch file that will run from a folder and run a command in every subfolder?</p>
  
  <p>More details - I have school whose teachers are fulling the server with thousands of 10+ megapixel images.  I'd like to tell them to save to a set location then have a scheduled task run a batch file that will run a IrfanView command line in that folder and all subfolders to resize the images (IrfanView won't do it itself).
  I can figure out the IrfanView command line I need but beyond that I'm stumped.</p>
