But the error message in your OP showed what looked like a correctly 
formed path (apart from the quotes). Without a / or \ between dirpath 
and filename, the error message would have been different (probably 
about not being able to find the file).

When I was creating such path-handling routines, anything returning the 
name of a path /always/ ended with \ or / for that reason: so that you 
could just stick a file at the end without needing to check whether the 
path had the right ending or not.
