Getting iTunes to display all the music in a folder.
Got a new computer (Windows 11) & installed iTunes, but only about 1/2 of my music files are now displayed in iTunes. My music files are on an external HD (ExtHD/iTunes/iTunes Media) & ALL of these albums were formerly visible in iTunes before moving to the new computer.
It looks like music purchased thru the iTunes Store shows up in iTunes, though with the little icon suggesting the need to download (the cloud/arrow symbol) despite already being on the external HD. Music downloaded from CDs doesn't show up in iTunes at all despite clearly being on the external HD.
Suggestions for getting iTunes to display ALL the music in a particular folder?
Thanks in advance.
Windows, Windows 10
