What is a Subfolder?
A subfolder, or subdirectory, is the part of a website containing a series of related content. Its URL begins with the site’s domain name, followed by the subfolder name, for example, https://yourdomain.com/subfolder-name/.
Site owners create subfolders for a clear website hierarchy and an easy-to-understand site structure. For example, a software company may regularly publish help articles and blog posts for its users and non-users.
Instead of publishing both types of content in the same folder, they could create a subfolder for the blog posts at https://yourdomain.com/blog and a separate subfolder for the help articles at https://yourdomain.com/help.
