What are system memory dump files?
Memory dump files, otherwise crash dumps, are system files saved during blue screen crashes. When a BSOD error message appears, Windows saves a copy of the system memory. Those crash dump files can then assist developers to fix BSOD system crashes. They can hog gigabytes of hard drive storage.

What’s the difference between a crash dump and an automatic memory dump?
The difference between the two is not in the dump file itself, but in the way that Windows sets the size of the system paging file.
