I recently put the skydrive app on my windows phone and when I did it added 3 new folders to my albums section of my pictures on my phone, 1)camera roll from skydrive 2)mobile uploads from skydrive 3)saved pictures from skydrive. I'm confused though because Ive never put any pictures in these folders yet they all seem to have a random assortment of all the pictures on my phone. Whats controlling what pictures go where?
