Google Sites are great because they are easy to set up and can be used in a variety of different ways. Embedding a Google Drive folder on a Google Sites page is one of our favorite features, and it has a number of different use cases for a variety of different users.
For example, if you are using Sites to build a company intranet, you can embed a folder with all of your human resource documents. On the other hand, schools can use this feature to create a destination for students to find important information on a class project.
To ensure all of your users can gain access to the documents in the folder, be sure to set your sharing permissions to anyone within your organization can access.
