Files with the .MDMP extension contain compressed data that comprises a post-failure memory dump of a Windows application.
MDMP files are created by the system and are usually used to debug programs because they save information about errors. Windows usually creates uncompressed HDMP files in parallel with MDMP files and can use them to report errors to Microsoft. Analysis of MDMP files is possible thanks to WinDmp, which is part of the Microsoft Windows SDK package.
