At the top of the **Camera Calibration** panel, the buttons enable you to load, save or clear camera calibrations in your Tracker system.

As noted in [Calibrating Vicon cameras](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556330), the camera calibration files that are saved after a completed calibration are not permanent and can be overwritten. If you want to keep a calibration so that it is not removed from this folder, you must save it.

If you want to extract the .*xcp* from a motion capture file (.*mcp*), such as one from a captured review, you must load that review and save it.
