More fascinating for me is this discussion thread, where there's legitimate debate around the need/expectation for alphabetical sorting to match/include lexical sorting.

I'm personally in the "want lexical as part of alphabetical" - as 'photo19' should come after 'photo2' in my expectations, but the number of cases cited where this doesn't/shouldn't work is enough to justify a degree of contextual or situation awareness that most systems and interfaces simply aren't designed to cater for (file-systems vs photo-storage applications).
