We have to change content in the .html helpfiles.
I extracted the Help.chm using the HTML Help Workshop(hhw.exe) with the File-decompile option.
After changing 1 or 2 html files for testing ,I tried to compile but it asked for a hhp file. So I created .hhp file using New-Project and added the .hhc,.hhk & .htm files to be incuded .(When I decompiled the Help.chm it extracted .html,.hhc,.hhk files)
When I compile this new .hhp to Help.chm, its size is 571 KB. But the original Help.chm is 879 KB.
Also If I decompile the original Help.chm it says “575 files extracted”. But the new Help.chm when decompiled says “570 files extracted”.
Please let me know if you have any inputs on this.
