have you looked at the file under notepad to see if it was just a text file? a lot of old-school databases were put together that way and the extension dbs was only used to indicate it as part of a database.

if it's not just text, you might be in for a bumpy ride. i just got finished (maybe a year ago) writing a parser for a really old school pascal created database file to migrate it over to VB. i hope you're good at codebreaking, because that's all it really is.

if it's a newer format, i don't know anyone who knows anything about it. have you done just a web search? that might be your best bet.
