How to delete raw and jpg files simultaneously?

[millan]

I tried to set up my 5D3 in order to write raw files on CF card and jpgs on SD. The playback was set on SD card. When I delete picture, the only jpg file from the SD card is deleted, raw file stays untouched on the CF. How to arrange to delete both, raw and jpg files simulaneously?

If you're writing to separate cards, you cannot.
