Heroic game files

Hello!

I'm having a hard time finding any game files from my heroic installs.

I have three games installed, two Linux and one windows game. They all run well and the save games persist, but after looking absolutely everywhere in the file structure, I can't find absolutely anything:

Inside /games/heroic/ there's absolutely nothing, no prefix folder or anything, even though that's the install path.

I haven't been able to find it all those compatdata or whatever folders.

Could it all be buried deep inside the heroic install folder?
