If one of the file names had been valid for the mainframe, I'd not have asked. Now it is valid, keep it that way.
The path stuff is where you are by default, or where you can change directory to, when you have actually logged-on to the other system, using your userid and password. As enrico has pointed out, you've failed to specify anything to attempt log-on/connect or anything like that. The way you want to do it, before you ask, is the way that others do it at your site.
