“… i want to save all data of the people made the course ?”

I’m kind of confused, as there seems to be some word missing. Do you mean….

“… i want to save all data of the people who made the course ?” (People who developed the course.)

or

“… i want to save all data of the people who made through the course ?” (People who finished the course.)

Trying to understand your question, because it is very short.

A Captivate project, cptx or cpvc (for Video Demo) extension, is a ‘raw’ file, it will contain everything you have put in that project: graphics, audio, static objects, styles, video, animations, scripts… It may even have more data in the Library than what is used in the project. When you publish the project (you don’t export a project) it is the same as for a website: it will be made ready to be used on a webserver or a LMS where the learner has access by launching a html file. Similar to websites. That includes also reducing file size by compressing a lot of files and changing their format. You can compare this with the compression of a raw photo (extension RAW) to JPEG, or with compression of a raw audio file (WAV extension) to MP3.

From the second sentence I try to conclude that you are talking about gathering information about the learners who took your course, maybe took a quiz etc… That functionality is normally taken over by a Learning Management System. Such a LMS will manage the learner accounts and their gradebooks to say it in a very simple way. It is not the goal of Captivate itself, which is an eLearning authoring tool meant to create courses, which can collaborate with LMSs compliant with SCORM, AICC or xAPI protocols (sort of communication language between the course and the LMS). There are ways to achieve this using an internal server instead of a LMS but that will mean the necessity of server-side programming.
