With the release of Office 2008 for the Mac and (I think) 2007 on the PC Microsoft introduced the .docx file type. I have no problem with it, but I no longer use Office only Google Docs. The problem is that from what I can tell Google Docs will not import .docx files … when I get one via email I am out of luck. But a couple of links emerged today … the first is the utility that Microsoft itself provides to change the file types. Simple application that is downloadable from the Microsoft site. The second, and I haven’t tried this one yet, is a site called Zamzar. It looks promising, allowing you to convert files into dozens of formats via the web. So the next time you get a .docx and need to work with it, there are option.
