file numbering reset - help please!
I put a card from my S45 into my 20D and it automatically changed the file numbering to a much higher value. I want to set it back to the last folder number used on the 20D.
I've noted the method for resetting file numbering on compact flash cards in thread
But the EOS viewer program won't allow me to change the folder name or image name when the card is in the camera. Searching my system doesn't show the camera as a connected drive - it's only visible through the Canon software. I also saw a program called Downloader Pro suggested, but this is for PC only, and I have a Mac.
Does this mean I have to buy a seperate card reader before I will be able to change my file numbering? Is there any way I can change the file and folder number if the card is in the camera.
Thanks in advance...
