title: count files in specific folder and display the number into 1 cel
body: <p>I am trying to know how many files there are in 1 specific folder with .xls extension.
  I read hundreds of examples with message boxes, but that is not what I'm looking for.
  I just want to have the number displayed into 1 cel.</p>
  
  <p>Is there someone who likes to help me with that please?
  I can not post any attempts because I can not get started :-(</p>
  
  <p>best regards,
  E.</p>
