Hi,
Local sites have no obligation to be in the c:\wamp\www\ tree, they can be on another partition or disk.
At home, Wampserver is installed in e:\wamp64\ and my local sites are in g:\www\.
The VirtualHost DocumentRoot will tell you where the local site is.
For example, in the file: e:\wamp64\bin\apacheapache2.4.58.1\conf\extra\httpd-vhosts.conf
<VirtualHost *:80>
ServerName mes-photos
DocumentRoot "g:/www/phottello"
<Directory "g:/www/phottello/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
It is also possible to create one or more junctions in c:\wamp\www\.
