This is a diagram of PE runtime data structures. I used OmniGraffle. I will post the OmniGraffle files when I get ahold of them again. They are on another computer.
I was inspired by Ero Carrera's  diagrams and Corkami . I made this diagram because I was teaching myself Windows data structures and was unsatisfied with what was out there. The information for these structures was obtained from "Windows Internals 6" by Russinovich, Solomon, and Ionescu .
It is not finished, but I figured I should just upload it now instead of whenever I get around to finishing it. Hopefully I haven't made any mistakes. It will probably go through many iterations, maybe end up being interactive.
