how do i find the toribash folder on the steam version?

Easy way: right click TB on steam games list - > click properties - > go to local content tab (or something like that, it's the last tab I think) - > click "browse local files" or something like that. I don't have steam on so I can't tell you exactly but you should do fine.

Hard way: it's somewhere in your steam folder\steamapps\common\toribash

Or just search "Toribash" while you are in the folder where you have steam, it's the fastest way.

I'm not using steam version, unsure how to get to it in steam version, may be different, or not
Shouldn't be that different.
