Re.video pics being downloaded to my laptop?

HI GUYS, I AM TRYING TO DOWNLOAD IDEO PICS FROM MY SONY HANDYCAM TO MY WIFES LAPTOP AND MINE. CUTTING IT SHORT, IT LOOKS LIKE MY CAMERAS HARD DRIVE IS FULL UP OF VIDEOS AND BOTH OUR C DRIVES HAVENT ENOUGH SPACE TO TAKE ALL. OUR D DRIVES ARE EMPTY AND HAVE STACKS OF DISK SPACE THAT MAY BE ABLE TO TAKE MOST OR ALL OF THE VIDEOS, INFACT I WOULD PREFER TO SEND THEM TO D DRIVE AS I GOT THE SHOCK OF MY LIFE WHEN I FOUND OUT HOW MANY DVD DISKS WERE REQUIRED. I HAVE A BRAND NEW SEPARATE HD I BOUGHT ABOUT 5YEARS OR SO AGO BUT HAVENT USED IT YET, I WILL LOOK AT IT L8R AND SEE HOW MUCH MEMORY IT HAS. GETTING BACK TO MY PICS. I DONT KNOW HOW TO EITHER LOAD MY CAMERA'S SOFTWARE AND/OR VIDEOS OR PICS DIRECT FROM MY HANDYCAM TO MY PC D DRIVE, AND I DONT KNOW HOW TO TRANSFER EITHER PART OR ALL FROM MY C DRIVE TO MY D DRIVE. ANY HELP WOULD BE MOSTLY APPRECIATED. THANKS GUYS. JIMMY FROM ESSEX UK
