I have a WD 3TB MyCloud NAS drive connected to my modem/router via ethernet cable, and my Raspberry Pi 3B with DietPi and Emby Server also connected to the modem/router via ethernet cable (I followed these instructions
https://www.smarthomebeginner.com/setup ... erry-pi-3/).
I was able to access my NAS drive by entering "\\xxx.xxx.x.x\movies\" into the library section (the image the OP posted), and now it says the file path is "smb://xxx.xxx.x.x/movies".
BecauseI could point to the right folder, the server was able to download images and metadata ("save artwork and metadata into media folders" set to true), and I can see them in my browser (
http://192.168.0.15:8096/web/movies.html..), but when I look at the image and nfo files next to the movie files, they are all 0KB. I have no idea why the images and nfo files are empty, but still show up in the library.
I don't know if this is a DietPi issue, or an Emby issue, but I have Emby running fine on my PC, so I thought I'd try here for help first.
