About .qxf Files
QXF files are XML data files used by Q Light Controller+ to define lighting fixtures. They use the text/xml MIME type and store lighting fixture details in a structured format.
They include information on channel assignments, intensity levels, and other fixture properties.
- Fixture Definitions: The file holds precise configurations for stage or concert lighting setups.
- XML Structure: Its text-based format makes it human-readable and easy to edit with standard text or XML editors.
- Software Integration: It is used directly by Q Light Controller+ to load and calibrate lighting setups.
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 .qxf file used for?
A .qxf file is a fixture definition file used by the open-source lighting control software Q Light Controller+ (QLC+). It contains the technical specifications of a lighting fixture, such as DMX channel assignments, gobos, and color capabilities, stored in a structured XML format.
How do I open and edit a .qxf file?
The best way to open and edit these files is using the QLC+ Fixture Editor, which comes bundled with the Q Light Controller+ software. Because the file uses a standard XML structure, you can also view and edit the raw code using text editors like Notepad++, Sublime Text, or Visual Studio Code.
Can I convert .qxf files to other lighting formats?
Direct conversion to proprietary formats (like those for GrandMA or Avolites consoles) is not natively supported by QLC+. However, since the .qxf format is open XML, advanced users sometimes use scripts to parse the data into CSV or other open lighting standards.
Why is my .qxf file not appearing in QLC+?
If a file is not showing up, ensure it is placed in the correct user fixture folder (e.g., ~/.qlcplus/fixtures on Linux/macOS or the user documents folder on Windows). Additionally, check that the file extension is strictly .qxf and that the XML syntax inside is valid.
What is the correct MIME type for .qxf files?
Since .qxf files are based on the Extensible Markup Language, they typically use the text/xml MIME type. If you are configuring a server to distribute these files, you can refer to common XML configurations at mime-type.com.
Are .qxf files compatible with other operating systems?
Yes, .qxf files are cross-platform. Because they are simple text-based XML files, a fixture definition created on Windows will work perfectly on macOS or Linux versions of Q Light Controller+.
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.
