Folders are exclusive to PREMIUM and PLATINUM accounts. If you are a BASIC user and wish to benefit from this feature, please upgrade.
Folders are a way for you to organize your publications. They are also a way of selecting specific access for User profiles, Subscribers, and choosing which publications to display in your library widget.
PREMIUM users can have 5 Folders, and PLATINUM users can have 50 Folders.
