When scripture says, God "knows all things", does that include every action and decision every human will choose to make in the future?

I've often heard of the concept of Omniscience which is based on scripture that states God **knows all things.** > Isaiah 46:10 10 declaring the end from the beginning and from ancient times things not yet done, saying, ‘My counsel shall stand, and I will accomplish all my purpose,’ > 1 John 3:20 in whatever our heart condemns us; for God is greater than our heart and knows all things. > Psalm 139:4 Even before there is a word on my tongue, Behold, O Lord, You know it all. Does this quality of God include knowledge of everything that does not yet exist nor has yet occurred on the earth? More specifically: ***Does God already know every action and decision every human will choose to make in the future? How does this correlate with the objective truth that He has included free-will in the design of His creation?*** Please provide scriptural support.
