The easiest way is to watch the video, and the video file will be automatically saved to drive C. The saving address is to open the URL-> Tools-> Internet Options-> Internet Temporary File Settings-> View the file. But the premise is that the "used disk space" should be set larger, for example, 500M m. If it is set smaller, the video cannot be saved. The downloaded online video format is generally FLV. Looking inside, the file name is estimated to be a string of numbers. If you look at the latest date, the file size is relatively large, which is correct.

2 use the format conversion tool to convert the FLY file into rm format.
