Opening Office 2007 Files
Have you ever received a file from someone in the new .docx or .xlsx that you were unable to open? This is because Microsoft changed the file format in the 2007 version of Office. The new format offers smaller file size, increased security and the capacity for more features among other improvements. Unfortunately, without a patch, it is not compatible with older versions of Office.
If you are like a lot of people who still using Office 2003, you can go to Microsoft’s website and download the Office Compatibility Pack which allows you to convert the newer files into the older formats. If you do not have Office installed at all, you can also download free viewers from Microsoft. Just search for Excel viewer, Word viewer, etc.
