Assign Music, Movies, TV & Photo Libraries to external drive

With a fresh look at moving Music, Films & Photos off the local drive to an external drive.

Do we have to move the TV Library.tvlibrary / Music Library.musiclibrary / Photos Library.photoslibrary file as well or do we leave it on the HD?

I ask this because a TV & Music Folder keeps appearing when I assign the Media folder location to an external drive. The 'Pictures' (Photos) Folder has remained empty (except for the photolibrary file (app))

Have looked at other posts and they are all years old. As I am running brand new iMac (M1 Chip) with latest 11.5.2 Big Sur, there must be an easier newer way.

Thanks in advance.
