How to convert corel draw cdr file to PDF using command line?

I was writing that in a hurry. What I was trying to explain is that if you know you need the exact pdf settings every time you want to produce a pdf from cd all you have to do is record a macro to do it. One button click and all is done for you. Publishes to a specified directory with a specific name i.e. Untitled.pdf. I even included a password protection in the pdf and also included as part of the macro is code that will copy that file. Then all you have to do is navigate to where you want to save it then paste and rename.
Sounds like a long process in itself but if you did it manually each time you're talking about 20-30 clicks and typing and such.
My macro is one click then find where I want to paste the file and rename it.

Thank you for your reply. But I need to do it automatically . I want a hot folder, when cdr files come, they will be convert to PDF files without any hand operation.
