access the content of the sd card through a usb cable plugged into the camera as if it were a mobile

None of the cameras I've had so far actually required a transfer program when USB-connected. The program just theoretically (to some degree or another) streamlines the transfer process by hopefully keeping track of what's been transferred before and what's new.

All my cameras just show up as a storage device when I plug them in. You can usually specify how they're to appear - As a camera, drive, whatever. They're "drives" and I just copy from them. I've never had a reason to copy anything back to the camera, though.

Len,

If I understood dostoievsky correctly, he wants to transfer or copy an image from his camera to a computer or mobile device on the fly, so that he can rename them and then transfer them back to his camera without ever taking the memory card out of his camera.

I don't know how you could rename the files in camera because there are no keys to input letters and numbers.

I personally think that the easiest way would be to take a bunch of photos, take the card out of the camera and put the SD card into a card reader plugged into a USB drive on your computer - but that's not what he seems to want to do.

You could create a new folder on your camera, and transfer all those newly re-named files back into your camera in your newly created folder, but I think you have to adhere to Canon's file numbering system in your re-naming process.

dostoievski needs to read up in his manual about how to create new folders on his camera, and how Canon uses a sequentially numbered file structure in their storage process.

I personally don't know why a person would want to undertake this kind of laborious process, but that's just me.
