I have NextCloud running on my RPi 4, and I have a bunch of video, music and picture files (many in folders) into NextCloud. NextCloud allows you to add files, but this is one by one and while you can make folders in NextCloud, I don't see any way you can add whole folders. There has to be a better way, but I'm not sure what it is. My understanding is that if you copy the stuff directly into the place where NextCloud stores its files, the files and folders won't be seen when you access NextCloud remotely. Anyone know how to get a mass of files and folders into NextCloud efficiently?
