Sur l'installation de MySql, il y a une note qui dit qu'il faut creer un My.ini ou un My.cnf...
This is a release of MySQL 3.23.49 for Win32.

NOTE: If you install MySQL in a folder other than
C:\MYSQL or you intend to start MySQL on NT/Win2000
as a service, you must create a file named C:\MY.CNF
or \Windows\my.ini or \winnt\my.ini with the following
information::

[mysqld]
basedir=E:/installation-path/
datadir=E:/data-path/

After your have installed MySQL, the installation
directory will contain a file named 'my-example.cnf'.
You can use this as a starting point for your own
C:\my.cnf file.

If you have any problems, you can mail them to
win32@lists.mysql.com after you have consulted the
MySQL manual and the MySQL mailing list archive
(http://www.mysql.com/documentation/index.html)

One behalf of the MySQL AB gang,

Je ne vois pas trop a quoi il sert (j'avais installer sur program file sans le creer et ca marchait)
quelqu'un a t'il plus d'explications ??
