Hi guys! I am a newbie. I have a Macbook Pro. I had a TON of movies that I have on my laptop b/c I post videos to Youtube. I just backed my computer up with an external hard drive. I then went and deleted all my movies under "movies" under my user. I also check iMovie and cleaned it out. I shut my computer down and restarted it. When I go to "about this Mac" and check the storage amount, it still says I have 300plus GB of movies on my storage. I don't get it. What am I doing wrong?? I want my storage cleaned up. Help! Thanks so much!
