Microsoft changed their 2007 Office formats from doc to docx, ppt to pptx, and xls to xlsx to support the XML file standard. This leaves many users of Office 2003 and Office 97 with the question of "How do I open these newer 'x' files?" One way to do this is to convert the Office 2007 docx, pptx, and xlsx files back to the older versions which can be opened by virtually any version of Word, Powerpoint, and Excel.
