PackageThis is an free open-source application that packages sections of MSDN or Technet Library to either:
.Chm -- HTML Help
.Hxs -- VS 2002/2003/2005/2008 Help
.Mshc -- VS 2010/2012 Help
It was started inside Microsoft but now members of the community are helping to update it via CodePlex. We still have more work to do. One problem users have is the temptation to download & package > 10,000 files. Microsoft themselves break MSDN up
into .mshc packages containing a maximum of 10,000 files each. If you stick to this maximum limit you should not have problems. But if you do see problems then please report via CodePlex.
