The dsn file extension is commonly used by many various database applications.

The dsn file contains settings, drivers and other parameters, that are used by ODBC drivers to connect to a specific database, such as Microsoft Access database or SQL Server.

To an ADO or RDS programmer, an ideal world would be one in which every data source exposes an OLE DB interface, so that ADO could call directly into the data source. Although increasingly more database vendors are implementing OLE DB interfaces, some data sources are not yet exposed this way. However, virtually all DBMS systems in use today can be accessed through ODBC.

How to convert file with extension DSN:

As far as we know, this .dsn file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
