Creating a new page for content requires the server to create a new file. The Path field allows you to select where that file will be stored. It also impacts the link to that page.

For example if you have a path called mypath and create a file called myfile then the link will become /mypath/myfile.php

Important Note Search Engines look closely at the paths and page names on your web site when indexing the site. Try to include some keywords in both the path and filename as this will help your site´s rank significantly.
