It supports saving PDF forms ( AcroForms), and import or export form data in FDF/ XFDF format. Its further development has been stopped in favour of the freemium PDF-XChange Editor. It was available in a free and a paid version. PDF-XChange Viewer (now superseded by the PDF-XChange Editor) is a freemium PDF reader for Microsoft Windows.
