Word 2007 - the file format
Word 2007 creates, by default, ”.docx” files rather than “.doc files”. If you need to share .docx files with users of earlier versions of Word, you can save as .doc files. If you do not have Word 2007 but have received .docx files — no need to worry. Just download the compatibility pack from Microsoft — allows older versions of Word to open .docx files.
When saving as .doc files Word will warn you about any features that are likely to be problematic. In my experience to date, Word has been conservative — warning about relatively minor problems.
