Office 2007 Word, Excel and Powerpoint use a new, XML-based file format.
"Introducing the Office (2007) Open XML File Formats"
http://msdn.microsoft.com/en-us/library/aa338205.aspx
If you wish, you can convert files in Office Open XML (OOXML) to the earlier
binary format, known as Office 97-2003 format. You can also set Word, Excel
and Powerpoint to save in the old binary format by default.
One of the advantages of OOXML is improved ease-of-access to the raw data in
the file. Depending on what your website is doing with the Office files, you
may learn to like the new format.
