i just restart my macbook right now after 15 days without shutting down or restart, i've noticed that before i restart, my used hardisk is 121 gb and my free is 111 gb, after restart, my used harddisk is 120 gb and my free is 112 gb, if you will noticed, i gained 1 gb on my free and lost 1 gig on my used, what happened or it is just a temporary files because i didnt shut down or restart my macbook for a long time?
Yup temp files cache files scratch disk file are deleted/cleared out upon restart... Pretty sure you should've performed a defrag or zap pram as well.... just to speed things a bit more... That is if you've copied and deleted a bunch of stuff...
