Remora USB Disk Guard is designed to be run from a USB drive and performs file encryption and compression. However it functions perfectly well from a normal fixed disk. It sits in the system tray and restores to a window that looks like a USB thumbdrive with 5 function buttons: encrypt files, encrypt folder, decrypt files, decrypt folder and configuration. Download the installer and extract to a folder of your choice. The application files are found in the {app} folder. Launch usbdiskguard.exe.
