A memory dump is taking all the information in your device's working memory (RAM) and creating a copy of it in your computer's hard drive. This process happens automatically when a computer crashes and right before the power turns off.
The Kernel Memory Dump file is written to %SystemRoot%\Memory. dmp by default.
Yes, it is definitely safe to delete Memory. dmp file. It is only used to identify the cause of system crashes so If the system crash was already fixed or the system is already stable then you don't have any use for this dmp file. I hope this helps.
The Automatic Memory Dump file is written to %SystemRoot%\Memory. dmp by default. The Automatic Memory Dump is available in Windows 8 and later.
Automatic Memory Dumps
dmp." This file contains the state of the operating system's kernel at the time of the crash. The kernel is the part of the OS that sits between the computer's hardware and the software that runs on it.
Memory Dump Files (.dmp files) are snapshots of a program's memory taken at a certain point in time, such as during a crash.
The DMP file is primarily associated with the MemoryDump or Minidump file format. It is used in Microsoft Windows operating system to store data that has been dumped from the memory space of the computer. Usually, DMP files are created when a file crashes or an error occurs.
Cause. This behavior occurs when more physical memory (RAM) is installed than the initial size that is set for the page file. If a STOP error occurs when the system is configured to generate a kernel or complete memory dump, no memory dump file will be generated.
When Windows OS crashes (Blue Screen of Death or BSOD) it dumps all the memory information into a file on disk. This dump file can help the developers to debug the cause for the crash. The default location of the dump file is %SystemRoot%memory.
When you delete a file on your computer and empty the Recycle Bin, your data does not entirely disappear. Although the file is no longer visible in its original location and your operating system possesses it, a copy remains on your hard drive.
The full process dumps caused by the "DumpType" configuration are not written to "C:\ProgramData\Microsoft\Windows\WER\", and instead by default are written to a "%LOCALAPPDATA%\CrashDumps" directory which is relative to the current user profile.
Locate the crash dump file in %LOCALAPPDATA%\CrashDumps. Note that if the crashing application runs under the System account go to: C:\Windows\System32\config\systemprofile\AppData\Local\CrashDumps.
Debugger command window
If WinDbg is already in a kernel-mode debugging session, you can open a dump file by using the . opendump (open dump file) command, followed by the g (Go) command.
You can find the blue screen dump file from %SystemRoot%\Minidump directory on your PC. If you don't see the file, the minidump file may not be enabled on your system.
A dump file is a snapshot that shows the process that was executing and modules that were loaded for an app at a point in time. A dump with heap information also includes a snapshot of the app's memory at that point.
Memory dump is also known as core dump, and blue screen of death (BSOD) in Windows-based computers.
dump command in Linux is used for backup the filesystem to some storage device. It backs up the complete file system and not the individual files. In other words, it backups the required files to tape, disk or any other storage device for safe storage.
