There's no simplicity in tar. Even reading the file size is a guesswork. It's a baroque format with weird short-sighted decisions patched and extended in ad-hoc ways by multiple subtly incompatible implementations.

Unless you're using PaX, isn't the file size just a fixed-size field in the header? Is there something I'm missing?
