howdy.

im downloading Kingdom Hearts 3,https://www.sounds-resource.com/playstation_4/kh3/.
how do you download all the sound files in Kingdom Hearts 3 at one click?

There's no way to download them all at once, unfortunately. You'll have to download them one at a time.

This thread will explain why you can't download all of them at the same time:
