How to transfert to SD card?

Hi all

I don’t find a way to write datas on SD card when inserted.

(the goal would be to duplicate SD cards to have another light backup)

Sorry. I think the data transfer only works one way - off the SD card to the MPW.

AFAICS you can copy anything to a mounted SD card or USB device from you desktop/laptop. Most likely you mean to copy something to the inserted SD card without the help of a host. Well, this would mean to select what to copy first and there is no way to do so right now. Well, this could be an improvement for any future device: having a small LCD might offer the choice to select a directory to copy to a SD card or USB device.
