Over the years, users have come to know Microsoft Office file extensions - .doc, .xls, and .ppt are probably the three most popular. With the release of Office 2007, Microsoft is planning on leaving those well-known augmentations in the past and replacing them with the new XML-based format that consists of 4-letter file extensions.
here is a comprehensive list of all of the formats and matching extensions.
2007 Microsoft Office system documents saved by using Office XML Formats have new file name extensions that allow Office to differentiate these file format documents from binary documents used by previous Office versions. The new extensions borrow from the existing binary file name extensions by appending a letter to the end of the suffix. The default extensions for documents created in Word 2007, Excel 2007, and PowerPoint 2007 using the new file formats append the letter "x" and are .docx, .xlsx, and .pptx, respectively. Other Office document types that use the new file formats (including templates, add-ins, and PowerPoint shows) also receive new extensions.
Another new change introduced in the 2007 Office release is that there are different extensions for files that are macro-enabled versus those that are macro-free. Macro-enabled documents include a file name extension that ends with the letter "m" instead of an "x. " For example, a macro-enabled Word 2007 document has the .docm extension, and thereby allows any users or software applications, before a document opens, to identify that it contains code.
