I noticed something today while I was looking at a series of podcasts I had downloaded from BBC Radio. The names of the files downloaded are like "(programme title)-yyyymmdd-(episode title)". This was surprising because I had never seen the order "(yy)yy/mm/dd" (which we Japanese--and probably people in some other Asian countries too--use) used in documents etc. from English speaking countries. Obviously, you need to use this order if you want the files to line up in the correct oldest-to-newest (or vice versa) order. Am I right in thinking that you only use this order in computer file names?
