What is an HM3 file?
An HM3 file is a project created by version 3 of EC Software Help & Manual, a Windows-based software tool used to create user documentation. It contains help pages written in Rich Text Format (RTF) and stores information about the structure and content of a help project, including topics, text formatting, and project settings.
More Information
Help & Manual was designed to make it easier for developers and technical writers to create consistent, structured documentation across multiple platforms. Users can create help pages and save them as HM3 projects to preserve their progress, and then export them to several different help formats, including WinHelp (.HLP), HTML Help (.CHM), WebHelp, and PDF.
EC Software released version 3 of Help & Manual in the early 2000s, and later versions of the software replaced HM3 files with the .HMX and .HMXZ formats in subsequent versions, which offered improved XML-based data structures and additional features.
How to open an HM3 file
