Ok so this happen twice already. I often check my finder to see how my hd space i have left. Sometimes i would download stuff and import video, and the available space would go down to 60 gb or so. then couple of days later i would go up to 90 gb remaining. This is the internal drive that came with my mbp. Now this would happen without me deleting any major files. In fact i don't think i deleted anything in the past couple of days. What the hell is going on lol.
