Dump files, with the extension .dmp, are often created when an application crashes and can contain information about why the crash occurred and what programs were running at the time of the crash. A memory dump file can hold all of the data in physical memory at the time of crash in Windows. The Debug Diagnostic Analysis tool comes installed with Windows. It can help you analyze .dmp files.

You can select individual dump files and run a memory or performance analysis on the files.

The tool will generate a report as a .mht file that can be viewed in a web browser.
