What is an ST4 file?
Project file created by the trial version of SuperCard, a high-level visual development tool for Mac OS X; stores a data document, which includes user interface components, program resources, and the logic that drives the interface; enables users to save projects while evaluating the software.
The trial version of SuperCard allows you to test the software without having to purchase the program. The ".st4" extension is used by version 4 of SuperCard but was replaced by the .ST45 extension, which represents version 4.5 of SuperCard. The full version of SuperCard 4 uses the .SC4 extension and the full version of SuperCard 4.5 uses the .SC45 extension. The ".st45" and ".sc45" extensions are used by later versions of SuperCard, as well.
