Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules.
You cannot distribute the ACT files either in a mod, as a mod or as a single file, doing so will get you more than a slap on the wrist, you have been warned.
