Website's Directory Structure:
Folders (Directories) are an important part of your web site. Folders are the containers for all of your website files. Remember that the browsers used to access web pages locally (on your computer) or remotely (on a web server that provides the page to users) cannot determine where on your computer a file is located. Since the web browser needs help to
locate your files, creating folders is a good idea. By creating specific folders that contain the various types of web page files (HTML, images, templates, java script, PDF, etc.) you ensure that at least YOU can determine where your files are and help fix broken links either locally or remotely.
