How might I change my mysql 'localhost' setting from (I think this is right) 'C:\wamp\mysql\data\test\mytable' to 'M:\wamp\mysql\data\test\mytable' (which is a backup).

This is from phpMyAdmin (if it helps any):

Server version: 5.0.41-community-nt
Protocol version: 10
Server: localhost via TCP/IP
User: root@localhost
MySQL charset: UTF-8 Unicode (utf8)
MySQL connection collation: Collation

Thank you,
Dave
