password protected directories

Ok I heard the best way to do this is by .htaccess

Now I have been trying to figure out how to do this and its not working.  Im using WAMP5

Here is my directory

D:\public_html\www

in the www folder is my website

now lets say I have this folder

D:\public_html\www\omgiwantthisprotected\

and I want the user name and password to me "test"

How would I do this?  I have google searched and everything but no luck.  My .htaccess file isnt finding my .htpasswd file.
