According to the manual, Shadow Files are to "speed up the editing of high definition video." But in my largest project, all the video was from a simple little Canon camera, not HD, just medium to low resolution .avi files. -- That project produced a large folder of Shadow Files for all the clips--. So--they aren't just for HD footage?--
Is it safe to now delete those files, turn off Shadow Files, but still be able to do more editing on that project?
