Organized Folders - What if you have music files on more than one disk (for space limitation reasons)?

Continuing the discussion from What's a watched folder? What's an organized folder?:

I have my music on two separate drives - one 6TB and one 3TB. I would experiment with Roon’s organized folders feature, but what happens to all those files - do they get spread over both drives? If I designate each separate drive as an “organized folder,” will the files on each drive remain on the same drive?

What happens to compilation albums or albums which are a collection of music from various artists? Do these get allocated over to the various artists’ names? Or do they stay together as a single album in the same directory?

Don’t use Organised folders, just add a 2nd watched Local folder pointing to the 2nd drive.

I thought so. Thanks. (See also this thread.)
