Reading only some results files in some folder

I am using the package DrWatson to run simulations.
I have one script writing many results files to some folder.
Now I want to be able to read only some of these files (e.g. one of them) and not all of them.
I am usually using collect_results() but it returns all of the files in that folder. Is there a way to read only one of them (or a few of them)?
