Based on what data? The FOLDER has been used for over twenty years to describe digital files stored together under some type of classification scheme. At least two major OSes for personal computers even use/d an icon of a manilla folder from an office to represent a digital folder. FOLDER is a legitimate term to use to describe a location, digital or physical, where things can be stored for easier locating. The term directory is far inferior as it implies merely a list of some sort, not a storage location. Even though some OSes now use the term directory rather than folder, it is a much inferior term and in my opinion is misused in OS terminology.

But then again, who really gives a rat's backside one way or the other? As long as people understand the meaning conveyed it matters not which term is used. Certainly not worth getting your penguin feathers ruffled.
