导致原因： 从IIS或者Tomcat之类的Web服务器通过二进制流下载文件时（比如通过设置Header为Content-disposition:inline），如果被下载的文件是Office2007的dotx,docx,pot等后缀的时候，下载对话框中的图标会变成ZIP的，相应的文件名也会成为zip为扩展后缀的文件。其实出现这样的情况，是由于IE中对下载文件类型的判断，假如找不到相应后缀的MIME的话，会自动根据数据流来判断文件的类型，而微软对Office2007的格式做了和以前完全不同的处理。 以前的Office文档是100%的二进制格式。第三方的工具操作起来非常不方便，而 Office2007从整体上都是基于XML格式的，这里并不是说Office2007文档可以保存成XML格式。而是Office2007默认的文档格式就是XML的（Word的docx、Excel的xlsx等）。也许有人会感到奇怪，用文本编辑器打开docx后，显示的仍然是二进制格式，并不是什么 XML。其实docx并不是普通的XML格式，当然，也不只是一个XML文件，docx本质上是一个zip文件，里面有一系列的xml、目录和其他的文件。如果我们将docx改成zip。就可以用winzip等软件将其解开。
解决方案： 在Server端添加MIME映射就可以了。如Tomcat , 修改/%tomcat_home%/conf/web.xml Xml代码:

下面收集了大部分文件的扩展名和相应的MIME对应，有需要的可以在列表中找到并添加。
