Wordpad may be a Windows component, but its documents can be directly opened
into Office, Open Office, Notepad ( a Windows component since Win 95), or a
number of other programs you can choose. So at least in that way it has a
"relationship to Word." Word documents could be opened into Wordpad or with
Notepad using the Open with dialgoue box from the right click context menu.
Windows Explorer is a Windows App, but it is tightlly related to IE, a
Windows compoent and both of them have relationships with OE and Outlook and
Office, and OE and Outlook have ties as well. All you have to do to open a
Word Pad document into Word (an Office app last time I checked is to add
Word or a number of document formats to the right click context menu as an
option to open the Wordpad doc as a Word document should you want the
functionality of Word-aside from pasting it there.
I guess it all depends what the meaning of relationship and nothing
whatsoever is, and what the meaning of "is" is as well.
