make folders with no access unvisible

Have you tried at just the parent folder that contains the folders you don't want the others to see, giving the user list just "Read" in the Work Area/Folder Security and "No Access" under Document Security?  This is what we do and it prevents users from seeing the children folders other than those that they have explicit access to.

Many Thanks Sean, That helped indeed.

Wish you all the best,
