File not found using wamp

I changed the port to 8080 on wamp in the httpd.conf file and it works, using localhost:8080. However, I don't seem to be able to open any file in wwww-folder, not even the index.php which supposedly is running when using the url localhost:8080!

localhost:8080/index gives me

Not Found

The requested URL /index was not found on this server.
Apache/2.4.9 (Win64) PHP/5.5.12 Server at localhost Port 8080

Has the path changed? How do I look this up?
