Hi, When I decompile my CHM file use microsoft html help workshop. It generates HHC,HHK and bunch of HTML files but no HHP file. When I create an HHP file using new project option and then compile it to create another CHM file. Now these two CMH files are not of same size and they behave differently. Am I missing something here? I am simply decompiling and re-compiling the same CHM file but the result is different.
