What is the Shared Folder Report?
This report offers a master view of all shared folders. You can click on the column headings to sort alphabetically or by user. You can drill down on each folder to see the particular sites and notes that are contained within, as well as all assigned users and the specific access rights granted to each (ie: hidden or visible access to the credentials, admin rights, read-only/write.)
This reporting does not show what is in the Shared Folders. For the ability to see what's in the shared folders we suggest using the SuperAdmin Shared Folders policy.
