My memory chip has jpg files, but several hundred new files in CTG format. I can see the images on the camera, but cannot open them when I transfer the files to my computer. What is the best way to open these images on my computer?

I can view the photoes via my camera which have the ctg extension. I can not down load them. As I have read in this string there is no way to recover them to a jpeg or other viewable format. Is that accurate?

If you can view your pictures on the camera, the jpg files are there. I found, when you have to many pictures saved on your sd card, more then a 1000, the canon camera is not happy about letting you download them to your computer. Take the flash card out of the camera and plug it into your laptop (if it has an SD slot) or use a card reader. No problem that way. The ctg file is only an index. Not the picture !!! After downloading the pictures to atleast two different storage devices such as Your computer and an external hard drive, they can be deleted from the SD card. I can not stress enought that you need atleast two backups. These are your pictures and a virus or a failure of one of those storage devices can lose them forever. A lot of people just buy another SD card and hope they will last forever on the card. They will not, and it's very easy to lose it. .
