A dump file, also known as a core dump, crash dump, or memory dump, is a snapshot of the memory of a computer program at a specific point in time. It is used to debug and analyze program crashes or other problems. Dump files can be created automatically by the operating system when a program crashes, or they can be created manually by a user or administrator.
Dump files can be very useful for troubleshooting problems with programs, as they can provide a wealth of information about the state of the program at the time of the crash. However, dump files can also be very large and complex, making them difficult to analyze. There are a number of different tools available to help analyze dump files, and the specific tools used will depend on the type of dump file and the operating system that created it.
