For the Form Designer Pro Filler you can only print files not save.
The FLCU Application is used to pre enter information so that a form can be created and opened by the Form Designer Pro Filler Application. In order to see what type of files are saved by the FLCU Application I entered in fake information.
For the FLCU Application a logo is needed for the the form to be created and there is a default open file for the log and other types can be opened as well.
