Hi,
You confuse url and path files.
PhpMyAdmin, as you can see on the homepage of wampserver (localhost) is launched by an alias. And it is in this alias that you will find what is the path of the PhpmyAdmin files.
Alias is wamp64/alias/phpmyadmin.conf. In thie alias you can find :
Alias /phpmyadmin "c:/wamp64/apps/phpmyadmin4.7.4/"
so, files are in directory c:/wamp64/apps/phpmyadmin4.7.4/
> I need to copy files into this directory
This is c:\wamp64\www\
But, you do not have to copy files directly into this folder, you have to create a folder, for example "c:\wamp64\www\mysite\", and put your files in this folder.
But, best for your local sites, is to use VirtualHost, see
