OK, let me try to explain. Music export in older versions had major flaws: it could only export artist nfo and art for album artists (not song artists that only appear as guest artists or on compilations) and assumed that the folder above the album folder was the artist folder, so could not handle collaboration albums (those with more than one album artist) or any other music file arrangement.
Whenever things diverged from the most simple folder arrangement export got it wrong, and moreover so did attempts scraping local artist art.
Quote:-to use kodi now, and as you suggest, i have to have all albums into directly artist folder
No, in fact the opposite. Kodi can now handle albums for an artist being in different subfolders that are not all number one unqiue artist folder.
The best local art and artist nfo solution to cover all artists and music file arrangements was to base it on there being a nominated folder for artist information - the Artist Information Folder - and every artist could and a subfolder in that just for artist art and NFO file.
So export was designed to work with that too. Export kind = "To Library Folders" demands that an AIF is set, and then sends
artist art and nfo to subfolders in the AIF, but
album artwork and nfo files go to the album folder
containing the music files for that album.
From what you have said what I think you want to do is
a) Set the Artist Information Folder in settings to some new empty folder away from your music files
b) Export with kind = "To Library Folders" ,
Items to Export = "Albums"
NFO files, Include art and overwrite settings as is your choice.
That will put the album.nfo and artwork including discart in the folders with the music files (what you call the "live folders") just like it did in previous versions.
If you also want to export artist.nfo and art as well then then set Items to Export = "Albums, AlbumArtists", but the artist stuff will go into the AIF into 683 separate artist folders each named with the artist name.
What it can't do is export artist stuff to folders
Music/A/A_artistname1/
Music/A/A_artistname2/
...
Music/B/B_artistname1/
Music/B/B_artistname2/
...
even if you are only interested in album artists and have manged to keep all the music by an artist in subfolders in a unique folder.
On the other hand, if your structure was
Music/A_artistname1/
Music/A_artistname2/
...
Music/B_artistname1/
Music/B_artistname2/
...
and folder name matched artist name you could take a slightly different approach.
But I would encourage use of a Artist Information Folder separate from your album folders and music files because it allows so much more flexibility.
