How do I download the square dances from Aqiyi on my computer to a USB flash drive? The ones I downloaded before it says the format is not supported and I don't understand it please advise the experts! Hello,

1, do not use Aikiye to download. The format it downloads is very special, the general player, can't recognize it, only the Aiki player can recognize it.

2, the general video converter, also does not recognize this format.

3, we recommend that you use other players to download, only to download the general format of the general external devices can support.
