The minidump file, which we will discuss in this post, is the smallest kind of dump file. However, only one of these is saved at a time and is overwritten when another crash occurs. Kernel Memory Dump files are also saved to C:\Windows\MEMORY.DMP file, the same as Complete Memory Dump files. When generated by the system, all old Kernel Memory Dump files are replaced and overwritten. Such files do not contain data from any unused, unallocated memory or the memory used by user-mode programs. Kernel Memory Dump files only contain data from kernel memory, which is why they are relatively smaller in size. When generated by the system, all old Complete Memory Dump files are replaced and overwritten.Ĭomplete Memory Dump files are saved to C:\Windows\MEMORY.DMP file. In this case, the complete contents of the memory are written onto the dump file. Types of Dump Files Complete Memory DumpĬomplete Memory Dump files are the largest of the dump files.
Windows can write debugging information in three types of dump files. With this information, you can understand how different dump files are created. It uses the Windows Page File and requires at least 2MB of free space. Kernel-mode call stack for the thread that stopped.ĭump files are created by copying the data off the system memory and onto the computer’s storage.Process information and kernel context (ETHREAD) for the thread stopped.Process information and kernel context (EPROCESS) for the process stopped.The processor context (PRCB) for the processor that stopped.The Stop message (error code), its parameters, and other data.The list below highlights the content which can be found inside a mini-dump file. Dump files can contain the following data in them, which can be helpful for the matter: Like Event Viewer, these files can be used to determine the cause of the error, and then use that data to fix it. Open and Analyze dmp files using WinDbgĬrash dump files, also known as “mini-dump files,” are system-generated binary files that contain various information about a crash that may have occurred on your computer.
