Hello, run WPP and connect to your wsus server. Then select the update and on the 'Information' tab click on the 'Id' Guid. This will open the right folder.
Note that you won't be able to change files here. Wsus will not let you do. You will need to make a new update to change these files. This is why when you revise an update, you start with the second screen.
