📌 Most frequently, the .HDMP file format label is designated for marking uncompressed and decoded error dump entries generated and opened by Windows Vista/XP when a particular program suite encounters crashes or errors. Specifically, the .HDMP file records include resulting “dumps” of the program state or condition when the error has happened and other appropriate system script has made a recording of the time of the error. Compressed and encoded Heap Dump schema entries are stored and maintained as Minidump (.MDMP) file extension nodes and may be responsively transferred to Microsoft as a compound part of a bug fixing and error reporting process. Windows Error Reporting parameters and tweaks are allocated in the Windows Registry at “HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Windows Error Reporting” branch. As a matter of fact, it is not expected that the user would reveal, uncover, open, and display the .HDMP file resource in the manual approach unless researching and investigating an occasional program failure which could result in the appearance of BSOD screen or fatal app crash in a controlled product environment.
📌 The .HDMP file logic and internal composition can be monitored, tracked, and opened by Microsoft Visual Studio IDE, which would perfectly fit for discovering and exploring all of the .HDMP covered error dump objects in a transparent, flexible layout and shape. The .HDMP file pattern is recognizable by Windows infrastructures solely of Vista or XP editions. More contemporary system revisions have switched from .HDMP mechanics to newer and more up-to-date principles and approaches to handle error state dumps.
