*.mdb file's consulting

[luoying050601]

Hey, I've downloaded the source data, but there's only data.mdb and lock.mdb file. But, I can't access them for lacking of the database's information.
something like this:

connStr = (

r'Driver={SQL Sever};'

r'Server=sqlserver;'

r'Database=bill;'

r'UID=sa;'

r'PWD=passwd'

)

I would like to know if txt_db stores sentences and img_db stores npz files?
