File Formats: New vs. Old

May 15th, 2007

By default, Office 2007 saves files in new XML-based formats. Word uses the .docx and .docm extensions. Docx files do not support macros, while docm files are macro-enabled. Presumably, this is to cut down on the number of viruses aimed at Word documents.

Similarly, Excel uses the .xlsx and .xlsm extensions, and PowerPoint uses the .pptx and .pptm extensions. Access has also changed its file format to an XML-based format, using the .accdb extension.

However, the new formats are not backward-compatible. Therefore, people using any older versions of Office will not be able to open files saved in the new formats. Since it will be some time before a majority of users have Office 2007, we recommend saving files in the old formats if you intend to distribute them to other users.

  1. Click the Office button.
  2. Select Save As.
  3. At the bottom of the dialog box, under Save as type:, select Word 97-2003 Document (*.doc).
