Why should I make CHM files for my software?

The CHM help file is a set of web pages written in a subset of HTML and compressed together with LZX compression. Nowadays, CHM is the most popular format for creating standalone help file for Windows applications, because CHM is optimized for reading and searching on a user's local PC.

Use CHM format to create context sensitive help for your application

CHM files are the most suitable way to quickly create a context sensitive help system for Windows applications. Almost all modern programming languages and development tools have built methods for linking your program source code with CHM file help topic. Those methods reuse HtmlHelp API by Microsoft that allows opening a specific topic or search for a specific keyword within the CHM file from your application.

No other tools are required to create CHM with Dr.Explain

You may edit your help content in natural way in a single application and then press just one button to make a CHM help file for your application in a couple of minutes.
