If you download a network video, you can use the small software Uume Spy to download it, copy and paste the playing address of the video into the capture box of the software, then click "Capture Now" to capture the downloading address of the video, right-click the address, and select "The target is another". Just browse and find your own USB flash drive, and you can copy it. In the address bar of your IE browser, right-click and select "Copy", then create a new text document on your U disk, double-click to open and select Paste, then ask whether to save it when closing, and click Yes.
