Doesn't this article explicitly point out a rather horrible Windows flaw, or maybe flaws? First, having an "extension" as a separate part of the file name has some bad consequences: you have to treat a file name as several parts. Second, having the file name (.exe, .bat. and some others) make a file executable or not. This seems to have contributed to Windows' malware plague by making it easy to fool people into running things. Third, confusing the application associated with a file and the file's internal layout seems like an unwarranted step, and this confusion is what the article under discussion deals with, no?
