"Linux" doesn't (or rather, there's underlying support but the application 
that lets you maintain that is desktop dependent).  But really it's not much  
different on Windows.  The only difference being that on Windows it's 
entirely dependent on file extensions, whereas Linux distros can use both 
content and extension.
