The Open file action opens the converted files in the default viewer. The application that is used here depends on your system configuration. By default image files are opened with the Windows Image Viewer and PDFs with the default PDF application.
You can also select to always open PDF files with PDF Architect, our PDF Viewer and Editor.
After the free registration you will receive an additional module which allows you to rotate, move and delete pages as well as merge PDFs. More modules to edit and work on PDF files can be purchased. Visit the homepage for more information.
