Nissim, If I had to guess, it was an oversight that it handles both folders and files. Any refactored version would have to not change the current default behavior. So, what I'd suggest would be a second constructor that allows you to set a boolean flag to put in a "file-only" mode and then add another validator that checks for the existence of a folder and that it is a folder, not a file.
