Private Disk Light creates one or more virtual encrypted drive for you to store documents or applications away from prying eyes. Each virtual drive is mapped to an actual file on your physical disk. Data written to it are automatically encrypted using AES with a master password that you provide. It is great for keeping data on portable storage devices secure so that sensitive information is not compromised when the device is misplaced or lost. Download the installer and install to the default folder. Then copy all files into a folder of your choice. In addition, you also need to copy C:\Windows\System32\dkar.dll. Finally, uninstall the program. Launch PrvDiskLight.exe.
