What is a DSN file?
The DSN extension refers to a Database Source Name file used by a host of database managing programs. The format helps the users connect to a database by listing their properties, such as the server address, user ID, password, data source name, and other relevant information. The ODBC (Open Database Connectivity) servers use the DSN extension to connect to SQL or Microsoft Access.
