You can try to google it! And if you don't find a video or a guide that works (which is unlikely) I have 1 question: Are you running Windows or Linux.
windows
Well that makes things harder....
yeah ... ._.
click win(windows symbol)+r at the same time and type in %APPDATA% then click enter then go to /roaming and then look for the logicsim folder and inside of that there should be the files and stuff.
thanks m8 :D
