File extension dsn is commonly used by many various database applications for various configuration or settings files. These can have a form of 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.
It doesn't seem these files are meant to be opened directly, they are settings.
These files are generally not meant to be converted to anything else.

Record marked as obsolete and not updated for a long time.
ISIS Schematic Capture was developed by Labcenter Electronics as part of its electronic design software. A dsn file contains the saved schematic, including the circuit symbols and their connections.
ISIS Schematic Capture is an obsolete Windows product. The format is mainly encountered in legacy projects.
Open the dsn file with the original ISIS Schematic Capture software on Windows. Because the product is obsolete, obtaining a compatible copy may be difficult.
If ISIS Schematic Capture can open the file, use its available export or print functions to create a static copy, or recreate the schematic in another design tool.

OrCAD PCB Designer is a computer-aided design suite from Cadence for creating printed circuit board designs. Its schematic-capture tools use the dsn file format to save circuit schematics.
An .dsn file can contain the components, symbols, electrical connections and other information that make up an OrCAD schematic. It represents the schematic portion of a PCB design rather than the completed board layout.
The format is associated with the Windows version of OrCAD PCB Designer. Related project, library and layout files may be needed to work with every part of a design.
Open the .dsn file in OrCAD PCB Designer on Microsoft Windows. Use the suite's schematic-capture tools to open the design and edit or inspect its contents.
If the schematic uses external symbol libraries or project files, keep those files available in their expected locations so that the design can load correctly.
Open the schematic in OrCAD PCB Designer and use its available export functions to create another PCB format, netlist or schematic exchange file.
Exported data may not preserve every OrCAD-specific schematic feature, so retain the original .dsn file when full editability is required.
