About .qxm Files
QXM files are specialized XML files used by Q Light Controller+ for MIDI templates.
They store mapping data that links MIDI hardware to lighting parameters. This allows users to control lighting rigs via MIDI devices.
- Main Use: Q Light Controller+ MIDI template configuration.
- Format: An XML-based text file, indicated by the text/xml MIME type.
- Software Support: Open them with Q Light Controller+ or any text editor that supports XML.
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 .qxm file?
A .qxm file is an input profile used by the open-source lighting software Q Light Controller+ (QLC+). It contains XML data that maps the buttons, sliders, and knobs of a specific MIDI hardware controller to functions within the lighting software.
How do I open a QXM file?
You should open these files using Q Light Controller+ to utilize the MIDI mapping. Since the file is based on the text/xml standard, you can also open and view the raw code in any text editor like Notepad, TextEdit, or Notepad++.
How do I install a downloaded QXM file into QLC+?
To use a custom profile, move the .qxm file into your user 'InputProfiles' folder. On Windows, this is typically located at C:\Users\YourName\QLC+\InputProfiles, and on macOS, it is found in ~/Library/Application Support/QLC+/InputProfiles.
Can I edit a QXM file manually?
Yes, because it is a plain text XML file, you can edit it manually to tweak MIDI values. However, it is generally easier and safer to use the built-in Input Profile Editor tool inside QLC+ to avoid syntax errors.
What is the difference between .qxm and .qxw files?
A .qxm file is strictly an input profile for hardware controllers (MIDI mapping). A .qxw file is the main QLC+ workspace file that saves your entire lighting show, including fixtures, scenes, and chasers.
Why does my web browser display code when I open a QXM file?
Web browsers detect the underlying MIME type as text/xml. Consequently, they render the file as a structured XML tree rather than launching a lighting application.
Are QXM files compatible between Windows, Mac, and Linux?
Yes, Q Light Controller+ is cross-platform software. Because .qxm files utilize standard XML formatting, a profile created on Windows will work perfectly on macOS or Linux versions of the software.
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.
