Change datadir for MySQL 5.6 on Windows XP

[Touko Djeumou]

Hello guys,

I need some help, please.

I want to change the data directory of my MySQL server (version 5.6) on windows XP. There is not a my.cnf file in my MySQL base folder and in c:\Windows. Even a search for all files containing the term "datadir" doesn't find that CNF file.
There is a CNF file (my-default.cnf) in the MySQL base folder. I have change the value of datadir inside but it doesn't have any effect. Indeed, I still obtain "C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.6\data" when I enter SHOW VARIABLES LIKE 'datadir' with mysql.

Any idea?

Thanks
