What are memory dump files? On Windows computers, the system will automatically generate a file named “.dmp/dump/minidump” file each time your computer experiences a system crashing like BSOD. These files can help you identify why your system crashes and prevent it from happening again.
The small .dmp files contain the memory information, the stop error code, kernel mode, processor details, a list of loaded drivers, and so forth. Usually, the Windows 10 dump file location is usually in either the directory of C:\, C:\minidump, C:\Windows\minidump, or %SystemRoot%\Minidump.
However, the problem is that there’s no Windows built-in tool to read and analyze minidump files. If you want to read .dmp files, you need to install a memory dump analyzer like WinDbg, NirSoft BlueScreenView, etc.
