In Resources, there is only a Folder and Sub-Folder. You can have a number if Sub-Folders to a Folder, but no Sub-Folder within a Sub-Folder.


You can create Folders and Sub-folders in Resources through Web Portal, by going to Resources > Folders > + New Folder.


Or Resources > Sub-Folders > + New Sub-Folder.


Note: To create a Sub-Folder, you will need to have a Folder that it will go under.
