Thanks for remembering about Cuis. In Cuis, we haven't payed much  
attention to FileSystem functionality yet. Most likely our code is  
rather outdated here. If Squeak decides to switch to FileSystem, I  
think Cuis can do the same. In any case, we need to review  
alternatives and pick one for Cuis, but we're not in a hurry.
