Excellent. Remember that you should also look at the super classes for
methods. UnixFileDirectory is the instance of "FileDirectory default" but
it's also a subclass of FileDirectory so the methods you can call include
UnixFileDirectory and all the methods on the class hierarchy including the
methods on FileDirectory. Please see the method categories on FileDirectory
that I mentioned.
The question I asked was a bit different. When you ask for the #entries of
the instance "FileDirectory default" what class is each file?
By the way, based on the question you asked there is a method on
FileDirectory to determine if the file exists before you read it (it's in
the method categories I pointed out to you). What is that method?
All the best,

I get an instance of UnixFileDirectory. And there are only 6 methods for
UnixFileDirectory, none of them doing what I want.
