By default, Dreamweaver creates HTML pages using the .htm extension (such as index.htm). If you prefer to have an .html extension appended to your filenames by default, you can edit the appropriate configuration file, and edit the file extension attribute.

Note: To learn more about filename extensions and how they relate to document type definitions, see "Extensible document types in Dreamweaver" in the Extending Dreamweaver online Help.

To change the default file extension:

  1. Locate the MMDocumentTypes.xml file in the Dreamweaver application folder in the Configuration\DocumentTypes folder ($Dreamweaver\Configuration\DocumentTypes).
  2. Create a backup of the MMDocumentTypes.xml file.
  3. Open the MMDocumentTypes.xml file in Dreamweaver (or any text editor).
  4. Change the order of the HTM and HTML attributes in the winfileextension and macfileextension XML tags of the documenttype element.

  5. Save your changes to the file.
  6. Restart Dreamweaver to initiate the new settings.

    By default, Dreamweaver will now append the .html extension to HTML files.
