You need a char with enough strenght (more than 10 in my experience, you can use Shadowheart to do this).
Simply click and drag the item you want to move, it works with pretty much every item you can find on the ground, including the ones you find in containers and corpses (you can drag them out, for corpses it may requires to hit the "loot all" button after doing that).
