Also note customs paths create a sub-folder /metadata so if you point it to x:\metadata everything will go to x:\metadata\metadata.
Sub-folders were done because people were pointing cache and metadata to the same location.
I wanted to comment on this - currently, I have album-related artwork (cdart.png and folder.png) getting saved directly in the media library folder for a given album. Meanwhile all artist-related artwork (logo.png, banner.jpg, etc.) is going into a new new subfolder Library\metadata\artists\[Name]. Can the "metadata" folder be bypassed so that new artist artwork goes directly into the appropriate library folder? If not, I suppose I could simply copy those new artist folders into my root Library directory to achieve the same thing.
So ideally I'd end up with:
...etc. (underlined files are already showing up exactly where I want with current settings )
In any case, thank you so much to all involved for making Emby Server happen, and particularly the robust fanart scraping. I was banging my head against the wall trying to get this done in Kodi!
