Yes, the documents will open in their default applications, provided they
are on the user's system.
Once they are imported, create a normal hyperlink to the files. Upload all
the files (the *.pub, the *.doc and *.html files). Click the link of the
*.doc file - it will attempt to open within Word (if word is on the users
system, otherwise will prompt to download the file if it can't find an
application to open the *.doc file in.
Same with Publisher.
On
www.microsoft.com there is a "Word Viewer" that will allow users to view
the Word file (similar to Adobe Acrobat viewer)
I don't know about Publisher files; the user may well need the Publisher
application to view the file, unless you convert the *.pub to *.pdf (modern
versions should be able to do this if you have Adobe Acrobat (full
application), or there are third-party apps to convert to PDF on the 'net.).
