I have a copy program that copies Korean dramas onto my desktop. How can I transfer the file directly to a flash drive instead of copying it to a blank dvd? I can copy the dvd from the dvd drive to my flash drive but it does not include the sub-titles. I want to watch the K dramas on a flash drive during flights to save the battery on my laptop which does not have a dvd drive. And need the sub-titles to understand the dramas. Help!!
