What is a CPTX file?
A CPTX file is a project file created by Adobe Captivate, a screen capture application used to create multimedia eLearning products. It contains one or more slides that may include screen recordings, audio, or other interactive content. The file is used for authoring learning management system (LMS) products such as software demonstrations, simulations, and quizzes.
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.
