Calm down.  I&#x27;m not asking for a badge of certification whatever whatever.  I just don&#x27;t understand what the complaint is and therefore cannot evaluate it.<p>[Since you asked, the biggest complaint in my filesystem-centric Windows experience is that filesystem drivers are very &quot;heavy&quot;.  There is not really a layer like Linux VFS which can handle common bug-prone tasks before they get to your driver.  The driver is expected to do a lot.  But I don&#x27;t think drivers are easy on any platform.]
