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 .qhelp file used for?
A .qhelp file is an XML-based document used within the Qt framework to organize help content. It stores structured data such as topic outlines, keywords, and navigation details to help developers integrate documentation into applications.
How do I open a .qhelp file?
Since it is a plain text file, you can view its contents using any text editor like Notepad, Notepad++, or Visual Studio Code. To use the file for its intended purpose, it must be loaded into Qt Creator or processed by Qt help tools.
Is a .qhelp file the same as a .qch file?
No, they serve different stages of the documentation process. A .qhelp file is an XML text file used for structure and configuration, while a .qch (Qt Compressed Help) file is a binary format optimized for viewing in Qt Assistant.
What is the MIME type for .qhelp files?
The standard MIME type is text/xml because the file strictly follows XML syntax. You can find more details about XML media types at text/xml on mime-type.com.
Why does my web browser display code when I open a .qhelp file?
Web browsers recognize the text/xml type and attempt to parse the file structure. Since the file does not usually contain a style sheet (XSLT) for formatting, the browser simply displays the raw XML document tree.
Can I convert a .qhelp file to PDF?
You cannot directly convert a .qhelp file to PDF because it primarily contains indexing data rather than full page content. You would need to compile the associated documentation project using Qt tools to generate a printable format.
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.
