DSN File Format

ODBC Data source

 

DSN (Database Source Name) is the extension attached to files used by database client software to connect, via an ODBC (Open Database Connectivity) driver, to a database. The DSN file typically provides the data source name and directory, the server address, user ID and password, and other information. DSN files often store that data as plain text, although they may also store it in the system registry.

The DSN extension is also used with an OrCAD schematic capture file, a SureThing Office Labeler document, a Surfcam file, a CD Stomper Pro file, an ISIS Schematic Capture schematic file, and an Object System Designer design file.
