A Windows minidump is a small file that is saved to your computer each time the computer stops unexpectedly, for example when you get a BSoD. This file is stored in the C:\Windows\minidump or C:\Winnt\minidump directory depending on your version of Windows. An example of a file name could be "Mini030409-01.dmp". In this example, 03 is the month, 04 the day, 09 the year, and -01 the number of the dump file.

How to view the Windows minidump

The Windows minidump files can be read using the dumpchk utility, included with Windows 2000 and the Windows XP support tools. For more information, see our dumpchk command reference.
