Calibre will create a needed folder.
No Folder. No Books (by author)
Needed: is all about the
Template you use
{author_sort}/{title} (I want my folders t o Alpha sort Ln,Fn
)

If you download directly to your device, download to an 'Unsorted' folder, then have Calibre
move them
D2D is not always a good idea. Some devices lock those away in storage that Calibre can't touch
. Others us a differing format than the PC download would get
YMMV
