Description

Many programs use .chm files for there Help files, these you can tell because the icon shown for the file is usually a document with a yellow question mark in the top right hand corner. These files are HTML files that have been compiled then linked to a table of contents which acts as an index.

Normally when you open a CHM file by double clicking on it, the Microsoft HTML Help Executable will open the help file so that you can view it.
