Whenever a Windows 10 system fails, it collects and records important information about the failure (such as when and what caused the failure) and saves it as minidump files in the minidump. By analyzing the minidump file, you can easily understand what caused the error. If your computer has recently failed and you want to know how and where to find the minidump files, follow the methods described in this article and you can easily analyze the cause of the problem.

What does the DMP file extension mean?

Windows memory dump files with the “.dmp” extension are system files stored in binary format. In case of any error or sudden failure of a third-party program or even system function, these files will be created automatically.

They record the details of the failure so that more advanced users can use .dmp files to troubleshoot problems with affected programs.

For example, if there is a BSOD (blue screen of death), details of possible causes (drivers or other software are often suspects) can be found in the automatically created .dmp file.

For obvious reasons, they are usually called “Memory.dmp” or “Crash.dmp”. They can be small individually in size.

However, as DMP files accumulate over time, they can take up a lot of disk space when they are linked together. This way, you can easily clean them with the disk cleaning utility.

Download and install the debugging tools for Windows

The tools are part of the Windows SDK for Windows. We just need the tools.

Go to the Windows Development Center to download the Windows SDK loader. It’s not a tool, it’s just a tool loader.

The installer is the loader of the entire SDK. We don’t need all the extra services, we just need the tools.

  • Click “Next” in the installer until you reach the screen where the packages are loaded with the title “Select the components you want to install”.
  • Clear all the checkboxes next to all packages except Debugging Tools for Windows.
  • Click Install.

Wait until the installer downloads and installs the packages. When the installation is complete, click “Close”.

Use the Windows debugger to analyze the minidump files.

Windows Debugger is a complex minidump file analyzer on your computer.
