Office 2007 is due to be released sometimes on 2007. Office 2007 will have two major changes to the office file format. For the first time Microsoft will have file extensions with more than 3 characters, but more importantly it will move from the well know .doc, .xls and .ppt file extensions for the popular Office documents.
Office 2007 will have a new, XML-based file format for Microsoft Word 2007, Microsoft Office Excel 2007 and Microsoft Office PowerPoint 2007. The New file formats will be the default file formats for Office 2007 but they will also be backward compatible to Microsoft Office 2000 using Office 2007 Compatibility Mode.
Some of the new extensions include
Word = .docx
Excel = .xlsx
Powerpoint = .pptx
