Difference between Editor pak's and UnrealPak pak's?

Thank you for the text file . But I am stuck at Step one. :~O What does this mean and how does one ‘get’ to it?

‘Go to %APPDATA%\Unreal Engine\AutomationTool\Logs\C+EpicGames+UE_4.18’

I see none of the %% Symbols anywhere on my hard drive!!

There CAN be no folders or files called: ‘C+EpicGames+UE’ Is it a location? A folder? A file? I am now more confused! I appreciate your willingness to help though, Maybe you could elucidate a little?
