Sdhd card

Are you using a program to view your photos directly from the camera? It's been a while since I had a computer that wouldn't read SDHC cards. I used to use the camera as a card reader. After plugging it in, I would open up My Computer and it would show up there as a removable device. I could open the device and all of the photos and videos I'd taken were there in a folder named DCIM. I could open that folder to view the pictures and videos, or I could select it and drag it to my desktop to copy all of the files in it to my computer's hard drive. I think you should be able to access all of your files that way if you're using Windows. If that doesn't work, you could buy a USB card reader that can read SDHC cards. They're usually pretty inexpensive. I think I paid around $15 for mine a few years ago.
