Unable to find my directory on apache server

[geminidude]

Hi,

I am running on macbook air Apache 2.4.16 version with php and mysql and am unable to locate my directory admin :-

Therefore when I type under the url

http://localhost/username/

The following page is displayed :-

Not Found
The requested URL /username/ was not found on this server.

What do I need to do in order to see my directory admin ?

There is no directory admin.

Thanks for your reply. What I meant say that I cannot locate my directory when I type in under the url :-

http://localhost/username/

Any ideas ?

I still dont understand what you mean. When i type http://localhost/username on my PC, this does not work either (of course not).

What do you mean by "my directory"?
