If you are looking to open the file and read what's in there... I have no personal experience with WhatsApp specifically, however the .db suggests that it might be an SQLite file. In which case you could try making a copy of the file (to not disturb the original state of it) and then trying to open it up with a tool such as http://sqlitebrowser.org/

Good luck.
