Where does Resolve 15 put the optimized media?

I've optimized or made proxies of my 4K media, multi-cam, but I don't know where Resolve puts the proxy clips. THe file path in the bin display column only shows where the original media is and I don't see a folder anywhere at the finder level that would contain the proxy clips.

Look in your project settings, master tab

Thanks.
