Can anybody suggest a program (preferably free) that would allow me to prevent any access to files within a specified folder or it's sub-folders? Perhaps entry of a password would allow access to the folder. I am using Comodo D+, Threatfire, Sandboxie, Defensewall at the moment but I don't think you can achieve this with any of these. Defensewall comes the closest as it prevents access by untrusted applications to the folder. However, I want to prevent access by any application. Thanks.
