In Windows XP, no matter when I uploaded pictures, it would upload numerous folders labeled with the date the pictures where taken, along with the pictures that where taken on that date. Now in Windows 7, anytime I upload it all goes into one folder. I liked how they used to sort folders by date taken not date uploaded.
if you look in the folder window, there is a "Arrange by" option. There you can cycle between Monthly view, daily view, and even rating and tags.
