What do you want more?
Something to backup your office files, or to learn from the source code of a program like that?
If you want a backup application, there's plenty out there.. Just a few keyboard clicks into Google and you'll be flooded with them. I use Backup4All Professional.
If you're looking for source code, there are a few websites out there like PlanetSourceCode.com that may have what you're looking for. If not, get bits and pieces from different codes and use your knowledge to blend it all together to make what YOU want
