What is a QHC file

QHC files mostly belong to Qt Assistant. An QHC file is a Qt Help Collection file used to store help documentation for Qt applications.
These files use an SQL-based internal structure to organize and index help topics, making search and retrieval fast.

They are generated and used by Qt Assistant for documentation viewing.

They combine help topics, indices, and navigation data in one collection.

You can open these files with Qt Assistant or a compatible Qt help viewer. For detailed information, visit Qt Documentation.

The SQL framework enables efficient queries and smooth access to the help content.

FilExt.com note: This file format is mainly for technical help documents but can be integrated into various projects to provide in-app documentation.
