I never realized that Windows uses a unix-like file hierarchy.
According to the article, drive C: is actually a symbolic link to \Device\HarddiskVolume4, COM3 is \Device\Serial0 and so on.
I'm surprised, frankly. My exposure to Windows is pretty much nil (and I like it that way) but I always assumed that the the C: drive and COM: stuff was a completely different way of accessing the devices and whatnot than what Unix uses. Apparently, it's actually quite similar once you get under the hood.

The NT object manager, doesn't that have more in common with VMS than UNIX?
Linux's sysfs is similar, in ways, but neither of these are unix-like unless... um, all hierarchies of objects are unix-like?
If you're sincerely interested in OS internals, you should expose yourself to other systems without prejudice. Otherwise, everything "tastes like chicken".
