While publishing, a window opens that asks if you want to publish all pages or just the pages in the folder. So using folders is convenient if you have draft pages that you do not want to publish — you can add these to a separate folder (you can name it Draft) that won't be published. If you choose the "Only in this folder" option from the project, when you are outside of folders, then all pages are published except those assigned to the folder. Read more on how to create folders
in our guide.
