i know with 2003 office the help files where all in CHM format.  i can't find any on 2007 even though it looks the same.  Does anyone know what format it uses and where they store it. Or is there a repository that might have it in chm format?
Watch Question

They are using Office (2007) Open XML File Formats.

In mine they are storing in this location C:\Program Files\Microsoft Office\Office12\1033

i see all the help files, they have .hks extension...how can i open
Hello Jason,

Office 12 Online help (help located on the server) is AP Help (Assistance Platform help as used in Windows Vista Help and Office 2003 online help).
Office 12 Offline help (help located on the local PC) is MS Help 2.x (same help system used by Technet, Visual Studio 2002/2003/2005 etc).

AP Help
The AP Help SDK is part of the Vista BDD 2007 (Business Desktop Deployment) download. AP Help is not support by Microsoft, it's for OEMs and MS in-house. Microsoft do not encourage us to use it in any shape or form (unless we are an OEM or are helping an OEM).  I see no technical problems with using AP Help except that's it is not a mature technology and not ready for prime time yet.
Windows Vista AP Help.

MS Help 2.x
MS Help 2.x we all know about. The problem here is that the default mode for Office 12 is Online help. It's easy enough to merge content into Office12 Offline Help (so your help content appears in Office TOC, Index, Search etc), but the user may never see it because they are configured to view Online help.
Then there is the whole question about if I extend the Office GUI via the Office extensions how to I call my help? I don't know the answer.

thanks for the read.  what i am angling at is using robohelp to decompile some of the microsoft help files and customize them for my own end user manual.  It decompiles the chm files easily..trying to figure out how to do 2007
you have to think about your the target file format (CHM?) for your users. I never tried to decompile to load edited content to a users machine.
The Help 2.0 SDK (also known as Help 2.0 Workshop), is required to compile your help source to Visual Studio compatible help (.HxS) files. It is important to note that MS Help 2 is designed primarily for Visual Studio help integrators. It is not for creating general application help.

Please read all the information from the link above about "Authoring for Office 12 Help". But you maybe warned - I never did this but I think it isn't easy to do. Deep in help authoring bits ..
See also FAR a tool for handling both HTMLHelp 1.x (CHM) and Help2 files.
