Comment Box in Properties of Excel files
 

How can I put identical information in the comments section of
properties box (fileproperties) in 35 files? I put the date the file
was distributed for reference purposes. That way I can, or anyone else
can, just hover over the file name in Windows Explorer and see what
date it was sent out on. I don't want to put it in any other part of
the properties except the comments section. Can anyone help me?
