Changing to the mysql\bin directory.

Hi
Can anyone help me with this small, but niggling issue.
Everytime I go to the command line and go to the "mysql"
directory I have to take the long way to get there. By this
I mean I have to enter the full path to the specified folder.
In some of the examples from books on mysql I notice that
"cd \mysql" is all that is needed to arrive there, but not for me.
When I try it this way I get the messege "The system cannot
find the path specified." How can I get around this problem?

Thanks in advance Paul.
