In the structure shown at the right, there are directories for each category of information within the website. This does not require that HTML documents receive mnemonic names because each is contained within it's own directory. Note that all the HTML documents in the website are called simply index.html . Content is managed by giving mnemonic names to HTML documents which contain various components of the website. This makes URLs to the content less obvious and makes the organization of the site difficult for a user to follow.
Content is managed by segregating it into a sensible directory structure.
This makes URLs to the content plain and the organization of the site much easier for users to follow. Generally the file names index.html , index.htm , home.html and home.htm are default names which will load automatically when an URL points to a directory name rather than a discrete file. Using the default file names makes URLs to the content on a website more intelligible to the user and easier to remember. Additionally, the default index file intercepts any user who enters the directory and forces display of the content it contains. In the example at the right above note that the default index file name is used in every directory of the website.
