Hello,

I downloaded the Witcher 3 soundtrack in the Extras area of Gog Galaxy.

Where did it actually dowload to? I can't find it anywhere.

I downloaded it now via browser but the question remains, where does Galaxy put the stuff it downloads?

Regards

Check the options menu. It should be in either the !Downloads folder of the games folder, or whatever you set it to.

You don't need the setup files to play the game. But the client may back up the downloaded files, so that should you ever want to reinstall the game (or migrate to a different computer) you can just copy the files, instead of re-downloading.

EDIT: I should clarify since I'm enough of a pedant to call myself out on this: you don't need the setup files any more, once the game is installed and playable. You certainly do need the setup files to play the game, but there's an intermediate step involved XD
