Yesterday I made a project with iMovie and started to import it as a QuickTime .mov file. I´ve set everything to the best quality and encoding, without compression. My HD had 101Gb free space. This morning there was an error warning that the project could not be completed because the HD was full. I checked and there's 0kb of free space! How do I fix it? Where do I look for files to delete? What shall I do?
