According to About This Mac, I have 111GB of movies somewhere on my Macbook Pro, running 10.10.2 Yosemite. My movies folders show only 5gb, as I am assiduous in either deleting or relocating movie files to an external drive. I have a total of 500GB but only have 9GB available and I need that space, but can't find the files to delete them. I'm pretty good with my Mac, but I'm no tech head, so please consider that when suggesting scary, potentially screw-upable suggestions. I have checked the caches, nothing significant there.
