Why is my iMovie 10.0.6 event so large after deleting the content?
I got my macbook air in October 2014 and I've been using iMovie since for my youtube videos. I have an event folder that says is taking up 30GB. I'm confused since when I double click it, there aren't any videos, files, or anything in it since it just links to my iMovie library where I've already deleted unwanted files. But when I put my mouse over the events and slide it from left to right I see all the video clips from my past youtube videos I've made from October 2014 to now? I don't have much space on my laptop and I need to free up any space I possibly can. I'm still new to OS X so I don't know much.
