What is an MDMP file?

MDMP files mostly belong to Windows by Microsoft. An MDMP file is a minidump generated when Windows operating system or a Windows application crashes. This file is similar to the HDMP and DMP crash dumps generated by Windows, however, it is highly compressed to minimize bandwidth use when sending an error report to Microsoft.Like other crash dumps, an MDMP file contains information about when the computer/application crashed, what processes were being run, the timestamp of the crash, stop messages, processor context, and the kernel-mode call stack for a stopped thread. Visual Studio can be used to read and analyze an MDMP file.

How to open an MDMP file

You need a suitable software like Windows from Microsoft to open an MDMP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MDMP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MDMP file directly in the browser:. Just drag the file onto this browser window and drop it.

Each file has a definite file format, that is, how the stored data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program.
