I use the front USB slot on the WD PR4100 to dump my camera card when it’s full.
It’s not copying the data to the shared folder I set-up called “Camera,” it copies to the “PUBLIC” folder, which I then have to transfer manually from PUBLIC to my CAMERA share folder, (transfer time is slow between share folders)
I remove the micro SD card from my camera.
Then place it into a USB Card Reader.
Put it into the front USB slot on PR4100 then select copy files on the machine.
Then when I come to view the images and video there in the wrong Share Folder, the Public.
