The file extension DSN is associated with multiple programs and applications and various file types. The programs and applications include OLE DB Provider, OrCAD, and ISIS Schematic. DSN files contain data and information related to the program that created the file.
If the file extension DSN is related to OLE DB Provider for ODBC, it is a database file type that contains information which is necessary for connecting to database environments. The content includes properties, source names, server names, directories, and connection drivers which assist with connecting to Microsoft Access or Microsoft SQL Server.
If the DSN file extension is created with OrCAD, the file is a CAD file type that contains circuit board designs for electronic configurations and devices. OrCAD is a Computer Aided Design program produced by Cadence Design Systems that provides productivity tools for design teams and circuit board engineers.
DSN files that are associated with ISIS Schematic are a CAD file type that contains schematic captures, PCB (Printed Circuit Board) templates, and technology data configurations. ISIS Schematic is an application created by Labcenter Electronics that provides a design environment for circuit board and IT infrastructure design.
How to Open DSN Files
Since DSN files can be opened with multiple programs and applications, double click on the file to see if it will automatically open in a default program you have installed on your PC. DSN files can consist of different file types, so you may already have a program which will open them.
If the file extension DSN is associated with OLE DB Provider and you are using Windows, the file can be opened with ODBC Data Source Administrator by Microsoft. IDBC Data Source Administrator is included with the Windows operating system and can be located in the Control Panel under the Administrative Tools category. For Mac OS X, you can use Apple ODBC Administrator to open DSN files. Apple ODBC Administrator is available for download on the Apple Support website.
If the file extension DSN is related to OrCAD, the file can be opened using the OrCAD program which is available in a paid version on the Cadence Design Systems website. OrCAD is compatible with Windows and Mac OS X. You can also use the ArchiCAD application, which is a Computer Aided Design program available on the GRAPHISOFT website. ArchiCAD is compatible with Windows and Mac OS X.
DSN files that are created with ISIS Schematic can be opened using ISIS Schematic Capture which is available in a demo version on the Labcenter Electronics website. ISIS Schematic is compatible with the Windows operating system version XP and higher. You can also opt to use the ArchiCAD application.
