I need help with iTunes. I am trying upload movies into my iTunes account so that I can upload to my apple devices to watch while I travel. All my movie are saved in my external hard drive. So what I did, I imortant to iTunes. First I open the iTunes then I click file and I click add file to library. The way I am doing it works fine. Here the problem. Since I have all my movies on my external hard drive. The minute I unplugged my external hard drive out. All the movies that I had uploaded to iTunes tell me that it couldn't locate the movies any more on my apple devices. So how do I do to keep the movies to stay on iTunes without me leaving my external hard drive plug all the time to my computer. Can someone please help me. Thank you
