What is a QB file?

QB files mostly belong to Qubicle. The QB file extension does not point to a single format but is used by different applications for distinct purposes.
For example, one type of QB file is a 3D model file used by Qubicle to store voxel-based models. This file format is typically built as a proprietary structure that may be in binary form. More details are available at the Minddesk website.
Another variant of the QB file is a Question Bank file used in exam management. In this case the content is rendered in XML, and the file serves as a repository for exam questions; you can find further information on the ExamView site.
A third type is used as a MURAL board data file, often created as a backup using ZIP compression to store collaborative board information (sometimes referenced as a Miro Quadrant backup). More details appear on the MURAL website.
It is important to use the intended software for the given QB file. The file’s internal structure—whether binary, XML, or ZIP—reveals its origin and purpose.
  • Identify the source of your QB file.
  • Check if the file has an XML header or ZIP markers.
  • Use Qubicle, ExamView, or the appropriate board backup tool based on the file’s origin.
  • How do you open QB files?

    You need a suitable software like Qubicle to open a QB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your QB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a QB file directly in the browser:. Just drag the file onto this browser window and drop it.
