The e-Capsule™ Private Safe is a family of "zero-footprint" products allowing to create and manage a proprietary file system for secure data encryption (AES256) capable of storing any number of files and folders, keeping them invisible to the PC operating system and inaccessible to unauthorized users. Within the e-Capsule™ Private Safe product family, the USB-U3 version is directed to owners of a U3 Smart device and users for which simplicity, data encryption and mobility are the fundamental requirements. With a U3 device you can carry your software on the same USB flash drive that carries your encrypted files.
