Why are there more types in my ntoskrnl binary than my fltMgr binary?

Question

I need the CONTROL_AREA Windows SDK structure to reverse fltMgr.sys. I see it in my ntoskrnl.i64 but not my fltMgr.i64 despite the fact they both only have ntddk64_win7 type library loaded. Why does my ntoskrnl project have 2500 types when my fltMgr.sys only has 400?

Answer 1

I needed to load the types from ntoskrnl.exe into fltMgr.sys using File -> Load File -> Load PDB File.
