Where DH File Go For Replay Mod?

I'm seeing like 3-4 different answers when searching around... is the folder I need for Replay mod suppose to be called "data" "replay" or "replay_data" for DH support? (then an overworld folder in that?)
Also do these folders go in .minecraft or in replay_recordings?

Solution

Ohhh, I think I see, it creates a specific folder for the replay in the Distant_Horizons_server_data/REPLAY folder that then I put the DH file in
