downloading/preparing them in the host also requires extra effects
before the test.

and we may also need testing tools, which are binary executables,
to aid our tests. then we have to wait for the improved rss.exe,
it is bad for the users/testers.

I just like to give the users/testers more choices to focus on the tests.
especially, for now it is a little hard to echo multiple files into guest.

I am also looking forward to the new version of rss with file transfer
functions.

Thanks for your questions, buddy.
