This document discusses process dump files, which provide a snapshot of a running process that can be analyzed to diagnose problems. It explains that dump files contain valuable diagnostic information but are static and cannot be directly debugged. Several tools are described for creating dump files, including Task Manager, ntsd.exe, ADPlus, and ProcDump. Visual Studio and WinDbg are both capable of analyzing dump files, with WinDbg generally being better suited for the task. Links to additional debugging resources are also provided.
