The 2007 Office Suite Service Pack 2 adds support for extensible file formats. Office Word 2007, Office Excel 2007, and Office PowerPoint 2007 are updated to include a converter interface that allows developers to plug third-party custom file formats into 2007 Office system applications. Developers now can create a converter for files of particular extensions. When this converter is installed on a user's computer, the custom file format behaves as a built-in file format. Users can open and save files in this custom format by clicking the Microsoft Office Button and then clicking Open or Save. Users also can set the custom file format as their default file format. For more information, see Introducing the Open XML Format External File Converter for 2007 Microsoft Office System SP2 (http://go.microsoft.com/fwlink/?LinkId=150645).

Before the release of the 2007 Microsoft Office Suite SP2, PDF or XPS file-saving capability was available only as an add-in; see 2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS (http://go.microsoft.com/fwlink/?LinkId=111590).
