How to convert full crash dump to mini dump

bsodcrashminidumps

I have a Windows 7 BSOD crash dump of almost 900 mb, and I would like to produce a mini dump from it. Is there a tool for that?

Best Answer

A dump can be converted with WinDbg:

  1. Open the full dump
  2. .dump c:\debug\dumps\small.dmp

You can automate this task by using cdb instead of windbg and pass commands via the -c "<command>" command line switch, e.g.:

cdb -c ".dump c:\debug\dumps\small.dmp ; q" -z c:\debug\dumps\big.dmp

The q ensures that cdb quits after re-dumping.
