Hello , I'm an owner of the Sony Tablet S1. I want to take my tablet with me on vacations so I can put my SD card from my Canon camera in my tablet to backup the photos onto my external HDD. I have a internal card reader , I have an mini usb ( with an otg cable) so I can hook up my 250GB external HDD. I can copy files from my external HDD to the tablet with file transfer and File manager HD and vice versa. I can copy files from my sd-card to the tablet with file transfer and File manager HD and vice versa. PROBLEM --> My tablet reads the SD card and the external hdd but I just don't find any app where I can copy files from the SD-card directly to the external HDD. Is there a good app / file manager which I can use to solve this problem ? Thanks in advance !
