I'm hoping to slim down the size of my 50gb iMovie library. I noticed that a huge chunk of space (like 20gb) is taken up by the contents of a "Render Files" folder in one of my Event folders.
You can see the "Render Files" folder by right-clicking/control-clicking your iMovie Library and choosing "Show Package Contents". Then open one of your Event folders. The "Render Files" folder is in there.
What's the deal with those files? Can I safely trash them? Will iMovie rebuild them?
