What is an SP45 file?
Data file used by SuperCard Player, an application used to execute SuperCard data documents (.SC45 files); associated with the SuperCard Player application by default, but has the same format as a SC45 project file; used for storing presentations, user interfaces, standalone applications, and other programs.
NOTE: SP45 files are not used as often as SC45 files.
