The MySQL server configuration wizard sets configuration variables values in my.ini file in the installation directory for the MySQL server. --defaults-file="C:rogram FilesySQLySQL Server 5.0y.ini" Path "C:rogram FilesySQLySQL Server 5.0" is installation directory of MySQL server . The --defaults-file option instructs the MySQL server to read the specified file for configuration options when it starts.
