What is an Mdmp file and how is it created?
An Mdmp file is a type of memory dump file that is created when a Windows system crashes or encounters a critical error. This file contains a snapshot of the system’s memory at the time of the crash, which can be used to diagnose and troubleshoot the issue. The file is typically created by the Windows operating system itself, and it can be found in the Windows directory or in a designated crash dump folder.
Mdmp files are created through a process called “dumping,” where the system writes the contents of its memory to a file on disk. This process is usually triggered by a critical error or exception that occurs in the system, such as a divide-by-zero error or a page fault. The resulting Mdmp file can be used by developers, system administrators, and support personnel to analyze the system’s state at the time of the crash and identify the root cause of the problem.
What information does an Mdmp file contain?
An Mdmp file contains a wealth of information about the system’s state at the time of the crash, including the contents of the system’s memory, the state of the CPU registers, and the call stack.
