Lower permission of individual folders below the level of the parent folder. I have 37 subfolders and had added the Architect to the parent folder so they could see all of them. Now a client ahs requested information in 1 folder is keptr confidential so I have to remove the access to teh parent foler and re add them to 36 differnt sub folders 1 by 1. If i could just remove their permissions for 1 folder it would be much quicker.
