How do I open docx files?

Hi there, docx is the new Microsoft Office Word document format, which Microsoft intends to replace the present doc format starting from Microsoft Office 2007 and onwards. If you don't have Microsoft Office 2007, don't fret. Simply head on to Microsoft.com and download the free Microsoft Word viewer. After installing the software, you should be able to view your docx file.
