A DSN file may also be a PCB (printed circuit board) design file created by OrCAD, a program used to design PCBs. It saves the circuit schematic and is often one of several files included in a OrCAD project ( .OPJ file). DSN files reference "symbols," which are the electronic components used to make up the design (stored in .OLB files).
More Information
DSN files are typically opened using OrCAD PCB Designer because they are created by the program. However, you can also import DSN files in Altium Designer as schematic files using the Import Wizard in the program.
