Changing DataBase Location


I need to change the folder for the em client data store , but I am having problems .

I read some guides to say move everything to the new store on D drive but leave the XML file in the orginal location .  Well … there is no XML file . And moving everything to the new folder just creates errors when em client is started .   So what has to stay in the original folder and what has to be moved to the new folder , as I cant get this working …

Thanks ,  Col
