About .qhp Files
QHP files are XML files used by the Qt Help Project. They use an XML structure, which is why their MIME type is text/xml.
Main Use Cases:
- Help Documentation Creation: They define topics, navigation, and layout for Qt-based application help files.
- Integration with Qt Tools: Processed by tools like Qt Assistant and Qt Creator to generate user-friendly help systems.
- Project Configuration: They set up and organize content that later compiles into a complete help collection.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .qhp file?
A .qhp file is a Qt Help Project file used by software developers using the Qt framework. It serves as the input configuration file, written in XML, to define the table of contents, index, and actual documentation files that make up a help manual.
How do I open and edit a .qhp file?
Since QHP files are text-based, you can open them with any standard text or XML editor, such as Notepad++, Visual Studio Code, or Sublime Text. However, developers typically manage them within the Qt Creator IDE.
How do I convert a .qhp file into a viewable help file?
You cannot simply "convert" it with a standard converter; you must compile it using the qhelpgenerator tool included with the Qt SDK. This tool processes the .qhp file and creates a binary .qch (Qt Compressed Help) file that can be viewed in Qt Assistant.
Why is the MIME type for .qhp listed as text/xml?
The QHP format adheres strictly to standard XML syntax. Because the file structure consists of tags and attributes readable by any XML parser, it is correctly identified with the generic text/xml MIME type on most systems.
What is the difference between .qhp and .qch files?
The .qhp file is the uncompiled source project file containing configuration data in plain text. The .qch file is the compressed, binary output generated from the QHP, optimized for fast searching and viewing by end-users.
Can I view a .qhp file in a web browser?
You can view the raw code structure in a browser because it is an XML file. However, the browser will display the document tree (tags and values), not the formatted help manual or the actual documentation content in a readable layout.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
