Folder Password Expert is a software tool that lets you restrict access to the folders that contain your sensitive data. When folders are password protected and locked, their contents cannot be read, copied, modified or deleted. To access a locked folder, you must supply the correct password. The password for the locked folders is not stored in the Windows registry or somewhere else on your computer. Unlike other utilities, Folder Password Expert will not allow to access the locked folders in Windows Safe mode, DOS, or other operating systems.
