Dependency Walker is a free utility that extracts a hierarchal tree of dependencies from any 32- or 64-bit Windows executable module (EXE, DLL, OCX, SYS, DRV, etc.), including those that were built for Windows CE. For each dependency, it lists all function exports as well as the exports that are actually being used by other modules (imports). Dependency Walker displays detailed information about each module including the full path to the file, base address, version number, machine type, debug information, and more.
