What is a CPTX file?

A CPTX file is a project created by Adobe Captivate, a screen capture application used to design multimedia eLearning products. It contains one or more slides, which may include screen recordings, images, text, objects, audio, or other interactive content. CPTX files are created to store various types of learning management system (LMS) product projects, such as software demonstrations, simulations, and quizzes.
