I share downloaded video files on my network to watch movies and TV shows using other devices. I have windows 10 on and alienware laptop and for the past month or so, it takes up to 3 weeks for new videos to show up. The files folders show up fine, but only the file folder with nothing in it. Then one day all of them will suddenly work. There has been the odd file that will take only a few days to work, but it's very uncommon. This came to be a problem around the same time that the computer had an update.
