Change basedir MySQL with xampp

I have installed XAMPP in my computer. I want change the "basedir" of MySql for default ./xampp/mysql/data. I will choose other directory in other disc. ¿Can you help me?

I'm spanish, sorry for my english.

 

There must be a my.cnf file somewhere. I think you can change it there.

 

Ok, I found this in "etc/mysql" thanks
