What Are System Error Memory Dump Files
After performing a disk cleanup on your PC, you may find that the system error memory dump files take up much space. You want to delete it to release some free space but you don’t know what it is and whether it is safe to delete it.
Actually, it is not hard to understand what the system error memory dump files are. When your Windows operating system crashes or encounters error like BSOD (Blue Screen of Death), Windows collects all available information stored in memory at the time of the crash and "dumps" it into a file, which is helpful to be used to diagnose the system error.
Here are four kinds of memory dump files. All of these dump files are stored on the drive where your operating system installed, normally the C drive.
- Complete memory dump: this type of memory dump file takes up the most disk space, as it contains a copy of all the data used by your operating system in the physical memory. Let me explain it to you with an example: If Windows uses 6GB at the time of the system crash, the memory dump will be of 4GB as well.
- Small memory dump (256 Kb): this type of memory dump takes up the least disk space. It contains very little information but it is very useful in the debugging process.
- Kernel memory dump: this type of memory dump is the 1/3rd the size of your physical memory. It includes the memory allocated to Windows kernel and hardware abstraction level.
- Automatic memory dump: this type of memory dump has the exact same size of memory of Kernel memory dump.
