What I don't understand is..
why does the backend need to provide a function for that in the first place?
I mean, we are already able to list the corresponding parent directory 
and provide flags for each element to tell if an entry is a file or 
directory.
So if the engine knows that there is an entry with the name xyz, why 
does it need to check if it's a dir or file? shouldn't it always already 
know?
