How to take back up and restore VB6 Source Code

Dear Friends,
I am using Office 2003 applications in my system, Now I am planning to install Office 2007 by removing the older version.
I used to have lots of small data conversion tools that I created in VB within the Office Word;
Please advice on how to take back up and restore VB6 Source Code before uninstalling the Office 2003.
Thanks,
Geraldine Carr
