DMP is a Windows dump file - a snapshot of memory written when a program or the whole system crashes, used to diagnose the failure. The Blue Screen of Death writes a .dmp so developers can later open it and see the exact call stack that brought Windows down. Analyser handles .DMP alongside related formats such as .PGP, .GPG, .SIG and more. In Analyser's format library, .DMP sits in the Email & security category.
