Convert .des to other format from command line?

I know how to convert a folder of .des files to other formats using a macro, but is there an automated way to run this? Is there a command line option to convert images in Corel Designer? I want to have a conversion run without the graphical program requiring a person at the computer.

I know this is possible with other programs such as Inkscape, but that does not work with new .des files. Does anybody know of a command line conversion program that works with Corel Designer X5 or newer files?
