By default, all software supports multiple file extensions. Office SharePoint Designer supports at least 34 different file extensions. The basic files that Office SharePoint Designer supports are .FWP. However, not all of the extensions listed on the list are always used to save the effects of work in Office SharePoint Designer. Very often, files with such extensions are used as source data files used by Office SharePoint Designer.
Office SharePoint Designer can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via Office SharePoint Designer and try to save it in another file format, also supported by Office SharePoint Designer.
