Need to read/convert QuarkXpress QXD fls

I have over 800mb of Presentations created via QuarkExpress ie *.QXD files.

Under windows need a program to open them.

I need a windows program that can view/open these files to see what they contain. Power point/Freelance Graphics, Word, Adobe WHATEVER. How can I possible read these files without buying an $800 Windows QuarkXpress for windows product
