I need some help with iMovie file management. I'm trying to free up some space on my 1TB internal iMac HDD. Currently, I have 19.9GB free. I have a 3TB external that I would like to move all of my projects and events too. I found this article which describes what sounds like an easy method of moving things around. Basically, hold down Command when you click on a project, and drag it from the internal drive to the external. When you let go, it asks you if you want to move just the project, or the project plus the events. I chose option two. With one of my projects, it said this would take up 71GB on the new drive. Great. Here's the problem: It move the project and events just fine, and everything works. But my internal HDD is still showing only 19.9GB free. Do I have to manually delete the events from somewhere on my internal drive? I took a look in my iMovie events folder and the event is no longer there, but it is on the external drive taking up 71GB of space. Any ideas?
