You can highlight your favorite folders by starring them, allowing you to find them easily without having to scroll down the folder list.
Your favorite folders are located right below the Protected Folder.
How to star and unstar folders
To favorite a folder, all you need to do is glide your mouse over it and a star icon will appear on the right-hand side. Then click on the star, and the folder will move to the top of the list.
You can star as many folders as you want.
You can also star a folder when viewing its contents by clicking on the star right next to the folder name at the top of the page.
Starred folders are a per-user setting. So if you are in a team, your teammates won't see your starred folders.
Finally, if you want to unhighlight a starred folder, simply click the star icon again, and it will move to its previous place in the list.
