What is a CUIX file?

CUIX files mostly belong to AutoCAD. The CUIX file is an AutoCAD customization file that stores menu and interface settings. It is a ZIP archive that holds XML files used by AutoCAD to build and modify its user interface.
Key details provided by FilExt.com:

Function: It defines menus, toolbars, and command interfaces within AutoCAD.

Format: The file is a ZIP-based archive, which means its content is compressed and can be extracted for review.

Usage: AutoCAD reads this file to load custom settings. Users can customize their tool palettes without altering the core program files.

Reference: For more details, visit the Autodesk Help page.

FilExt.com note: If you need to open or inspect a CUIX file outside AutoCAD, you can rename the extension to .zip and then extract the XML content with a text or XML editor.

A CUIX file is an XML-based customization file used by AutoCAD. It stores user interface elements such as menus, toolbars, ribbon panels, and keyboard shortcuts. These files allow users to personalize their AutoCAD workspace and streamline workflows by tailoring the interface to their specific needs. The CUIX format replaced the older CUI format, offering improved flexibility and organization. It's a core component of AutoCAD's customization features, enabling users to create a highly personalized and efficient working environment. This file format is classified as CAD Customization File.

If you can determine the file format, the associated program can also be determined. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the CUIX files looks like this:
