The top level client folder structure of Current, From Client and To Client is fixed in the current version, however, the Client Templates allows you to define a default subfolder structure to be used across all Clients in Nimbus, this includes any new clients added to the system will have this subfolder structure upon creation.
The green “Current" folder contains all client files, whether they are “published” or not, that only Staff (Employees) will see.
The yellow “To Client” is a shadow of “Current” but only shows “published” files that the Client can see.
This is just a convenient view for Staff to see what the Client will see, and it is not actually a physically separate storage area.
The “From Client” is separate however and will only contain file/s uploaded from the Client.
The idea of the dual From/To folders comes from the original implementation idea of Nimbus, this would clearly show Staff which way files were moving:
From the Staff to the Client.
From the Client to the Staff.
