If your main need is to lock a folder with stronger privacy than normal Windows permissions, GiliSoft File Lock Pro is built for that workflow. It helps restrict access to private directories, apply password-based folder protection, and secure sensitive content on local drives or removable media.
Folder privacy is still one of the clearest security intents on Windows. Many users do not search for broader access-control language. They simply want to lock a folder. This page keeps that direct search intent and maps it to File Lock Pro.
Folder lock is about blocking access. Folder hide is about removing the folder from ordinary view. In practice, users often start with folder lock when the main goal is stronger control rather than invisibility alone.
