It sorts my 497 movies in alphabetical order. You have to go into each file info individual to see which movie is on either my X: Y: or Z: volume. So it doesn’t seem to be a very useful sort function. Am I missing something?
There’s no actual „sort by folder“ option. Only an option to display a library by its folders. This will display the subfolders of your library folder(s) and let you drill into further subfolders (excluding the library folders).
