You need to either escape the backslashes (with another backslash) or
use forward slashes.  Perhaps most simply:

list.files(path = getwd(), all.files = FALSE)

don't forget the .Rdata file, history is separate.

Sure the message is there but it should have restored an empty
workspace so it should have absolutely no impact on your work.  If the
message really bugs you, add the --vanilla flag when you start R.  If
you are using a shortcut to R, you can add it there, if you start R
from the command prompt you can use it directly just like "R
--vanilla".
