The iTwin is a revolutionary USB device that allows users to access files remotely. iTwin allows you to securely access your entire hard drive. It's as if you are carrying an access-key to all your files in a device that fits in the palm of your hand. And unlike portable storage, iTwin lets your data stay put safely at home. iTwin is plug and play. Plug one half into an online computer and the other half into any other online computer and you are connected! View, copy, edit, and upload files to your computer. Data in transit is protected by robust AES 256 encryption. If you lose one half of iTwin, you can remotely disable that half. Your data resides on your computer not on someone else's cloud server. iTwin works with Microsoft Windows XP, Microsoft Windows Vista, Microsoft Windows 7, both 32-bit and 64-bit versions. It uses the familiar Windows Explorer, with drag'n'drop functionality. There's nothing to learn and nothing to configure.
