Computing the size of a directory is more than just adding file sizes

I never tire of reading Raymond Chen's The Old New Thing blog. . While sometimes he's way over my head with coding or API details, often his posts contain great explanations on some of the things that Windows does.

In a recent post, Computing the size of a directory is more than just adding file sizes, Raymond looks at why computing the size of a directory is difficult. The things you can put into a directory these days is a bit advanced from the days of DOS 1.0! And, to some degree, his post makes you want to question whether the concept of the "size of a directory" is actually meaningful.
