This is the home page of arCHMage. arCHMage is an extensible reader and decompiler for files in the CHM format. This is the format used by Microsoft HTML Help, and is also known as Compiled HTML.
Originally this utility was written by Eugeny Korekin, but since 2005 it has been maintained and developed by Basil Shubin.
You can contact me at basil.shubin [guess what] gmail [dot] com.
You can view example of decompressed CHM file here. I would be glad to receive freely redistributable CHM files for using as examples.
