I'm attempting to import a painfully large movie file to iMovie (46 GB), but when I attempt to import it, I receive an error message that reads, "There is not enough disk space available at the selected destination. Please choose another one or clear some space." All of my finalized projects are in iMovie, they take up 96 GBs (I think) but I cannot delete them, they're just there. I have no clue what to do. I've been searching the web for answers and have found none that work. Please, help!
