Hey guys. Ok so I felt like trying out iMovie today. A little window came up asking me to create thumbnails of every single video in my iPhoto library. So, I clicked Now and it went ahead and made thumbnails. I regret clicking Now because it wasted about 20GB of space and I want to know how to get those 20GB back. So, how do I get rid off all those thumbnails that I created? I feel like an idiot now because I can't figure out how to get rid of them. Help! Thanks for your help. EDIT: Now when I look at the videos in Finder, there aren't any thumbnails anymore!? What the hell! I am kicking myself now. Ok so I used iMovie today, created thumbnails for each video, I am completely regretting that now. It wasted about 20GB of space doing that. Also, thumbnails for things in Finder are gone! Like video thumbnails, file thumbnails, you name it. Gone. How do I get those 20GB back and what happened to all the thumbnails? I'm kinda angry right now because I did this now everything is messed up. Thanks for helping.
