If yes then this is one is for you! I had been searching for this software for a while and finally found it last weekend. It works a treat. Especailly as the thought of losing my memory key or someone accessing my computer could in effect almost takeover my whole operation. Folder Lock is free and an easy peesy install giving you pure protection from loss or theft of your usb flash drive (memory key) and computer. For more info - see Folder Lock. After downloading the free version I proceeded to buy the full version - marvellous 5 star software.
