I'm afraid that won't work. You must name the file gnubg_os.bd and keep it in 
the same directory as gnubg.exe. If you haven't got room on your C: drive, 
you'd better re-install it on your large partition.

Sconyer's database is a separate product that must be bought. Changing these 
settings will have no effect for you.
