This is precisely the facility provided by a memory card.Memory cards are often referred to as the Cerebria digital version of films. But unlike films, memory cards are so much more flexible in that they not only store images, they also allow you to transfer the images from the card to your PC. After the images have been transferred to the hard disk of the computer, you have the option of deleting the images from the memory card, thus clearing up memory space once again for you to reuse.http://www.supplements4help.com/cerebria/
