Hide SubFolders

Is there a way to hide sub folders?  Say I have a root folder of C:\Data\Person\ and under there I have "Cases", "Documents", and "Other". When they log in I only want them to see "Documents" and "Other" and I want to hide "Cases". I have tried the RemoveSubFolder function with no luck.

As of v1.6, hiding subfolders is not possible but you can add or remove subfolder permissions with AddSubfolder and RemoveSubFolder functions. By adding separate permissions for a subfolder, you can restrict access without hiding the folder.
Please see this topic for more information:
