Pasting "%APPDATA%\Roaming\SpaceEngineers" into the File Explorer gives you an error because %APPDATA% is already the Roaming folder to Windows.
%APPDATA% is the Roaming folder, %LOCALAPPDATA% is the Local folder, etc.
Leaving it as "%APPDATA%\Roaming\SpaceEngineers" not only creates confusion, it is not the notation used on any of the other pages.
