A .mdmp file, short for Minidump file, is a crash dump file format used by the Windows operating system and other applications. It contains a snapshot of the process's memory and state at the time of a crash or unexpected termination. This information is invaluable for debugging and diagnosing software issues. The minidump typically includes details such as the call stack of the threads involved, loaded modules, and a limited amount of memory from the process. This allows developers to analyze the cause of the crash, identify the problematic code, and implement fixes. Unlike full memory dumps, minidumps are smaller in size, making them easier to share and analyze. They are often automatically generated by the operating system or application when a crash occurs, providing a crucial record of the error for later investigation. Analyzing minidump files requires specialized debugging tools and knowledge of the application's code base.
