Project file created by Adobe Captivate, a screen capture application used to create multimedia eLearning products; contains a series of slides, each of which can include screen recordings, audio, and interactive content; used for authoring learning management system (LMS) products such as software demonstrations, simulations, and quizzes.
CPTX files can be exported to a .SWF file, which can be played back in the Adobe Flash Player or other SWF-compatible player. They may also be exported to a standalone Windows executable (.EXE file).
NOTE: The CPTX extension was introduced with Captivate 5. Previous versions used the .CP extension. Adobe Captivate is part of the Adobe Technical Communication Suite.
