I have now come across 2 devices that play back audio files back in timestamp order; the timestamp they were copied to the device.
I have found that cp and konqueror [and Windows for that matter] copy files in a real ad-hoc order, thus making the preservation of playlist orders impossible. So I have had to resort to copying each file, one-by-one in the order I want, alphanumeric.
Is this to be expected by cp ?
I have had to write a script now to get around this in a easier fashion
my blog post about this.
