There’s a large portion of Windows system files which are not as easily accessed as some others. One of those Windows-exclusive extensions is known as DMP (.dmp) or Windows Memory Dump files.

Today, we made sure to explain the value of these files and, what is most important, the means to open them in Windows 10. If you want to access the DMP file in Windows 10, but you’re not sure how to, make sure to continue reading.

How can I access DMP files in Windows 10?

What DMP file extension stands for?

Windows Memory Dump files with the “.dmp” extension are system files stored in a binary format. If there’s an error or sudden crash of the third-party program or even system feature, these files are automatically created.

They store the details about the crash, so most of the seasoned users will utilize .dmp files to troubleshoot the affected programs.

If there’s a, say, BSOD (Blue Screen of Death), the details about the possible causes (drivers or other software are usual suspects) are to be found in the automatically-generated .dmp file.

For obvious reasons, they are mostly named “Memory.dmp” or “Crash.dmp”, respectively. Size-wise, they might be small individually.

However, as they tend to pile up over time, DMP files can take a lot of storage space when bundled. So, you can clean them up with ease with the Disk Cleanup utility.

How to open DMP files in Windows 10?

Now, opening these files isn’t exactly simple as Windows 10 doesn’t offer a built-in tool. There’s a good reason for this as rarely a common user will want to access them in the first place.

However, there are a few third-party utility tools which should enable you to open and read DMP files. They might look outdated, but in this case, we prioritise efficiency over the looks.

The first application is WhoCrashed, a dump file analyzer. This tool requires installation, but it’s fairly usable and has all the features you’ll need. You can even simulate the system crash (do this with caution) with certain parameters.how to open dmp files windows 10

It is a portable small-sized application so it doesn’t require installation. Once you get it, just extract it and run the EXE file. However, we’re rushing. Firstly, you need to let the system creating the dump files readable by the third-party software.how to open dmp files windows 10
