Do your .docx (Word 2007) files get renamed to .zip?
When you try to download .docx (Word 2007) files from the Internet, does Internet Explorer want to rename them to .zip files? If you’re looking for an easy fix, stop banging your head against the wall, it’s not you. It’s the server. You should contact the webmaster and ask him or her to add the Office 2007 mime types to the server’s configuration. With Apache running on linux, this is typically in the file /etc/mime.types. Ask them to add
application/vnd.openxmlformats docx pptx xlsx
to that file, and then restart Apache. If you’re testing it out on one of your own servers, you’ll probably need to close and restart your browser, too.
If you can’t get the webmaster to add the mime type, you’ll have to save the file to your computer and rename it to remove the .zip extension, changing it to .docx. Then you’ll be able to open it by double-clicking the icon.
