Install the Youku client, search the name of the video you want to download on the client, and check whether it is what you want first. Then there is a download button on the right side of the client playback interface, which can be downloaded by clicking it. Generally, the downloaded video format is FLV, which can be directly watched on MP4 old record player and other playback devices, and can be directly converted into the format you need when downloading. You can directly modify the folder of what you downloaded, that is, the download directory.
I hope this helps.
