Where does WordPress store the users customization in the theme

Good Day

When you are inside the wordpress ctrl panel, and you edit/create posts, do theme changes etc, where does WordPress store all that content? In which files?

Thank you

That information is stored in the MySQL database, not in files like you may be thinking of. They aren’t stored in .php or .html files.

If you want to “see” how and where that data is stored the easiest way is to browse the database using a tool like PhpMyAdmin.

NOTE: Technically, there are files associated with the MySQL database but they aren’t easy to get to and you can’t read them except through the interface provided by the MySQL engine.
