By default, articles and files in Admin Area are displayed in ascending date updated order. That is, the last article or file updated is at the top of the list, and the first one updated is at the bottom.
Sometimes you want to see the list differently. You can order by date added (newest date first), date added (oldest date first), date modified (newest date first), date modified (oldest date first) and in alphabetical order.
