I'm a new CMSimple user that I'm discovering and testing. A real pleasure

With the study of the documentations and the help of these forums, I manage to understand and get results but of course I have a lot of questions as you can imagine. Lol!
My first tests made me break the site and I know it will happen again before I master the CMS. So my first question is...
Is there a way to reinstall it cleanly without deleting files and folders and emptying the database, which would avoid having to reinstall the modules and themes already in the system?
Thank you.
