Quick Look Filter for QuarkXPress is the file previewing technology built into Mac OS X 10.5. It allows you to view files right in the Finder without actually opening them, and it even provides large previews for the neat cover flow feature that the Finder inherited from iTunes in Leopard.
This filter provides this functionality to QuarkXPress 7.x files.
