Quiz on MySQL data directory location, structure and relocating data directory’s.

The MySQL data directory, also known as the datadir, is where the database files are stored. It contains the databases, tables, log files, and other essential data for the MySQL database server. 

The default data directory location for MySQL on Windows is: C:\Program Files\MySQL\MySQL Server 8.3\data and C:\ProgramData\ Mysql. 
The C:\ProgramData directory is hidden by default, so you need to change your folder options to see the directory and contents. 
The default location for storing database files in MySQL is /var/lib/mysql. However, this location can be overridden in the configuration file. 

You can change the data directory when installing the server or before running it. For example, you can unpack a MySQL Zip archive distribution into a temporary location, then copy it data directory to where you are setting up the new instance.
