For people who wanted to convert all their MS Office documents to the ECMA OpenXML file format *soon to be ISO ratified* in a batch process, this download will speed up your organization's migration. IT'S FREE!!
Don't worry, it wont modify your orginal binary files, it will just create new XML equivalents in a separate folder. There is no downside, unless you think files that take up half the size is bad. *yay*
