Recently, we did a PC replacement from someone who was on Wordperfect and Quattro Pro and updated them to the latest version of Office 2007.

While Word will automatically convert WPD files on the fly, we found out fast that QPro will not.  Luckily there is a simple convertor you can download for free from Microsoft (why it is not embedded is beyond me).
