I am trying to use Daemon Tools for Mac to combine audio files into a disc image (in Mac OS High Sierra 10.13.3). When (having clicked the appropriate toolbar button for audio images) I choose a folder from which to import the files, I see a window where my files appear. A button above this window, with an image of six squares, promises to allow me to "change the item arrangement" and suggests I "hold down the option key to change the sort." In fact, however, no matter what I do, the files in the resulting disc image are always in the same order (I think by creation date) and not the order I choose (by name).

Am I doing something wrong?
