.DMP File Extension
File TypeWindows Memory Dump
This file is saved in a binary format, which requires a specific program to read its contents.
A DMP file is a file that contains data "dumped" from a program's memory space. It is often created when a program has an error or crashes and may also be saved by the program "Savedump.exe" on the first reboot after a crash. DMP files are usually named "Memory.dmp."
Windows memory dump files may be used for troubleshooting system errors and other problems. However, they can take up a significant amount of space and may often be deleted.
