This is what the path should look like. You need to rename the highlighted folder to Multiplayer, but to access the contents of the h5m file, you'll need an archiver. Or you can change the extension to zip, then the system should open the archive automatically, and, of course, after the changes, you need to change the extension back to h5m.
