Although we appreciate this security tool's speed and ease of use, a few security gaps prevent it from being a more solid option. Simply put, FolderProtecter lets you restrict access to folders and files by making them inaccessible or read-only or by hiding them altogether. The interface isn't necessarily snazzy, but since it mimics Windows Explorer and lets you protect data via drag-and-drop transfers, it is a breeze to use. Since FolderProtector doesn't securely encrypt documents and folders, it works very quickly--although this means it's not ideal for use with top-secret information. Other users will need your master password to remove the program via the Control Panel or the Start menu, but we were able to access restricted folders by uninstalling the application via its Program Files folder. As such, this utility is best suited for folks who share their PCs with inexperienced users or small children who won't be able to discover this workaround.
From lbeily software:
FolderProtector is a new security tool that lets you hide, or restrict access to, your files and folders. Read-only files and folders also protect you from malicious programs including viruses, worms, and Trojan horses, and your files and folders cannot be deleted, damaged, or harmed in any other way. Even if a virus is introduced to your system, your protected folders will not be detected, infected, or harmed. FolderProtector does not change the file structure of the data, does not move the protected data, and does not change Windows system files. You cannot lose your files.
