What is DMP file?

Dump files with the DMP extension are used within Windows as space for storing information after system malfunction.

Additional information about DMP files

DMP files are usually generated automatically when an error or malfunction of system occurs, in order to diagnose and eliminate the problem. DMP file is created also with the „ Savedump.exe” program, during first system initiation after a malfunction.

Files are usually named „Memory.dmp”, but one may encounter also a different form, which also informs about the date of file generation - „MiniMMDDYY-00.dmp” (M – month, D – day, Y - year, 0 – following number).

Types of memory dumps

There are 3 basic types of data dumps generated in Windows:

  • full memory dump – after being created, all content of memory is stored within DMP file – it may cover large portion of disc space. They can be delated after diagnosis and solving of a problem.
  • system kernel memory dump – only the memory of kernel is registered. Memory assigned to programs is being omitted while generating DMP files. Similarly like the full memory dump, it is stored in the %SystemRoot%\Memory.dmp directory, and overwritten if another malfunction occurs.
  • small memory dump – it weighs only 64 kB and contains only basic information: parameters of the STOP line, context of PRCB processor, process data and kernel context for the stopped ETHREAD thread, information on EPORCESS process, and on loaded drivers. It is stored in the %SystemRoot%\Minidump directory, and it is not being overwritten.

Programs that support DMP file

We hope we helped you solve the problem with the DMP file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the DMP file (apart from the lack of the proper application installed).

First - the DMP file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the DMP file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the DMP file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the DMP file has not been completed and it cannot be opened properly).
