Loading *.db file into Database Browser in Windows 7 64

What is the procedure for loading a *.db database file into this Database Browser ?
I tried using ODBC Data Source Administrator to create a User Data Source
so that it shows up in the Connections list, but this program is still a mystery.

*.db file is mystery to us as well.
I can be paradox file or it can be SQLite file.
Database browser is 32 bit application so you should be using 32 bit driver.
If you want our help you have to provide more information.

How would you distinguish between paradox or sqlite file ?
Dumping out the first few bytes ?
A 32-bit driver for paradox or sqlite needs to be loaded ?
If not this application, which application is recommended
for run of the mill random database editing ?

If you email is your file we will have a look at it.
