What are MDMP files and how to open them

Are you having problems opening a MDMP file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your MDMP files.

What is a MDMP file?

Files that contain the .mdmp file extension are used to store information that has been dumped by an application's memory space after a system error or crash has occurred. These files are commonly referred to as "minidump files" and they are used for the Windows operating system in versions XP and later.

The data that is contained in these MDMP files is compressed and can later be sent to Microsoft to report errors within the software. Microsoft can then use the information in the files to debug the software application.

MDMP files are usually saved with an uncompressed HDMP version of the file.
