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. Users can send the crash dumps to developers when they file support tickets.
Memory dump files can waste a lot of hard drive space. They can hog gigabytes of hard drive storage. Windows only automatically delete crash dump files when HDD space is limited. However, users can also erase crash dumps with cleanup utilities.
