With the file extension DMP generally so-called Dumpfiles are marked. Dump is usually a copy of the memory contents of a device. The result of outputting this content to a file is called dullile.

Dump files are usually generated by the operating system automatically after a system crash. These files can be analyzed to find the cause. Dmp is not a real format, but just a memory dump. Therefore, it is important to know who created the file if you want to analyze it.

In general, DMP files can be viewed in a hex editor and, depending on the type, with a developer tool. It should be noted, however, that DMP files can be very large depending on the size of the memory and many editors can not handle files of several GB size. Most DMP files are only interesting for developers.

DMP files are mostly generated by Windows or Visual Studio and may vary in size depending on the setting. In addition to the small memory dump (64 KB size), there is the Kernel Memory Dump and the complete memory dump, the size of which depends on the system's main memory size.

Depending on the type of system crash, often no DMP file is generated. If you look at a blue screen with a percentage below it will generate a DMP file. After several such crashes it is recommended to delete them again. This can be done either through the system cleanup or programs like Pirisoft CCleaner.

How to open a DMP file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the DMP file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a DMP file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support DMP files. At this point we are looking for disk space where the application was installed in and we can link it with a DMP file. Since then, our operating system will use the selected program to support all DMP files.

Other issues

Despite the described problem with DMP there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the DMP file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the DMP file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
