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/Tracker41/pages/14321583), 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.

Loading and saving calibrations can be useful for:

- Comparing calibration changes
- Streaming data through Vicon Virtual System (see the [ ](https://help.vicon.com/space/VVS)*[Vicon Virtual System User Guide](https://help.vicon.com/space/VVS)*)


    **To manage camera calibration files in Tracker:**


- At the top of the **Camera Calibration** panel, click the required button:
  See the table below.

| **Button** | **Description** |
| --- | --- |
| Load | Displays the **Load Camera Calibration** dialog box, from which you can navigate to and select the required .*xcp* or .*mcp* file and click **Open**. |
| Save | Saves the current camera calibration. |
| Clear | Clears all camera calibration parameters and masks for the cameras. This enables you to recalibrate the system from a clean starting point. |
