For Microsoft product files, we can access the file
properties using code of the form:
myComment = ActiveWorkbook.BuiltInDocumentProperties
("Comments")

How can I read and write to the "Comments" property of a
non-Microsoft file, as displayed when you select the
Properties menu item of a file in say Explorer ?
This information doesn't appear to be part of the file as
a zero size file that has a comment remains size zero.
