Hmm, I was unaware that you could use a database software to create ebooks...
If your book is written as a database (
), there doesn't seem like a lot you can do with it. I highly doubt it's possible to map the contents of a .SNP suitably to ebook, since the internal composition isn't even remotely similar to (x)html. And you do NOT want to inflict images as pages for your readers!
Copy-paste what you can into MS Word, and work from there.
