When Windows encounters a serious system error that it cannot recover from, it may display a Blue Screen of Death (BSOD) and automatically create a memory dump file with the .DMP extension. These dump files contain diagnostic information about the state of the operating system at the time of the crash, including loaded drivers, running processes, memory contents, kernel data, and error codes. By analyzing these files, users and administrators can identify the cause of system crashes, driver failures, hardware issues, and software conflicts.
Memory dump analysis is one of the most effective troubleshooting techniques for diagnosing recurring BSOD errors. Whether you are dealing with random crashes, faulty drivers, hardware instability, overclocking problems, or application-related system failures, examining dump files can provide valuable clues. Windows 10 offers several tools for this purpose, ranging from beginner-friendly utilities that summarize crash information to advanced debugging tools capable of detailed kernel analysis.
This guide explains how to locate memory dump files, understand the different dump types, and analyze DMP files using tools such as WinDbg, BlueScreenView, WhoCrashed, PowerShell, Event Viewer, and other diagnostic methods.
What Is A Memory Dump File?
A memory dump file is a snapshot of system memory created when Windows encounters a critical error.
The file records information such as:
- Active processes
- Loaded drivers
- System threads
- Kernel information
- Memory contents
- Hardware status
- Bug check codes
This information helps identify what caused the crash.
Common Locations Of DMP Files
Windows stores dump files in specific folders.
Small Memory Dumps
Usually found in:
C:\Windows\MinidumpThese files typically have names such as:
061526-12345-01.dmpComplete Or Kernel Dumps
Often stored at:
C:\Windows\MEMORY.DMPThis file may be significantly larger because it contains more diagnostic information.
Types Of Memory Dump Files
Windows supports several dump formats.
Small Memory Dump (Minidump)
Contains:
- Stop code
- Driver information
- Basic crash details
Advantages:
- Small file size
- Easy sharing
- Quick analysis
Kernel Memory Dump
Contains:
- Kernel memory
- Drivers
- System components
Advantages:
- More detailed diagnostics
- Reasonable file size
Complete Memory Dump
Contains:
- Entire physical memory contents
Advantages:

Disadvantages:
- Very large file size
Automatic Memory Dump
Windows automatically determines the appropriate dump size.
Most systems use this setting by default.
Verify That Windows Creates Dump Files
Before troubleshooting crashes, confirm dump creation is enabled.
Open System Properties
Follow these steps:
- Press Windows + R
- Type:
sysdm.cpl- Press Enter
Open Startup And Recovery
