Can anyone help me with truebit os?

Why is it that when I create a new account with truebit os , I cannot find the folder where my private key files are stored? I entered all the steps according to this website : [https://www.reddit.com/r/truebit/comments/n3t4nk/tutorial\_how\_to\_use\_truebit\_os\_to\_mint\_and\_retire/](https://www.reddit.com/r/truebit/comments/n3t4nk/tutorial_how_to_use_truebit_os_to_mint_and_retire/)
