I think I would create a temporary directory & files and just run your code against that.

That way you don't have to mock the os functions at all. In your example it looks easy enough - just touch some file names. Of course if you need to do more complex things, maybe reading info from the files, you may have to keep a set of test files that you copy into your temp dir before you begin the tests.
