How do I clear the memory in my M447 camera and/or upload the pictures on my computer

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program, such as Picasa ( http://picasa.google.com ).

After downloading your pictures, put the memory card back into the camera and format it. This will clear the card and prepare it for further use. FixYa is full of people asking how to retrieve pictures from cards that haven't been formatted recently.
