how to import 100's of .dsf, and export them each as .svg

hello;

I am new to Corel.

I have about 500 .dsf files (from iGrafxDesigner ... maybe 1999 version).

I need to convert these to .svg.

I would like to avoid having to write an import/export script, but I have done scripting for AutoCAD, Rhino3d, and Lightwave3d, so if necessary I could do it I suppose.

QUESTION: what is the best practice to do this?

thanks.
