With the introduction of the new file extensions in the latest Microsoft Office edition (Office 2007) occasionally when trying to access or save these from within Internet Explorer, they will default to saving as a .zip file. Below are the steps to resolve this issue.
- Open Internet Explorer
- Click “Tools” at the top
- Click “Internet Options”
- Select the Security tab at the top of the window
- Click on “Custom Level” in the portion of the screen
- Scroll down until you locate “Open Files based on Content, Not file extension”
- Select Disable
This will allow you to save files that end with docx or xlsx correctly.
