What is an XMC file?

XMC files mostly belong to XMC Exam Tools, Mathcad. XMC files are used in two specific roles. They act as exam/homework data containers in exam management systems and as XML configuration files in some applications.

When used for exams, these files are generated by systems like XMC Test Generator, XMC Test Manager, or XMCExamTool. They store test questions, instructions, and other exam data for secure and organized delivery.

When used as configuration files, they rely on an XML structure. For instance, Mathcad uses an XML-based XMC file to save configuration settings. More details can be found at Mathcad.
