About the HTML Help compiler

The HTML Help compiler (Hha.dll) is part of HTML Help Workshop and is the program that compiles a project (.hhp), contents (.hhc), index (.hhk), topic (.html), and other (.gif, .jpeg, etc.) files into a compiled help (.chm) file.

The compiler provides these features:

• Source files are compressed into a compiled help file, which uses far less disk space than the original source files.
• Compiled help files can be distributed along with a software product, or they can be quickly downloaded from a Web site.
