During the motion capture workflow, you create a number of configuration files, Vicon Tracker generates a number of data files, and you can import files from and export files to other Vicon applications or supported third-party software.

You create and edit the following Vicon configuration file types during motion capture and analysis.

## Exportable configuration files

> Macro (scroll-tablelayout)

| **File type** | **Saved in** | **Description** |
| --- | --- | --- |
| .system | Menu bar, **System Settings** menu > Macro (inline-media-image) | Tracker system settings |
| .View | Menu bar, **View Settings** menu > Macro (inline-media-image) | View options and layouts |
| .vsk | **Tracking **panel | Vicon skeleton file |
| .mcp | **Tracking **panel | Motion Capture file. Same file format as the .mcp capture file but when exported from the **Tracking** panel only contains object tracking information and does not contain any 6DOF data. |
| .xcp | **Camera Calibration** panel | Calibration parameters file. You can create, reset, and load an .xcp file but the .xcp file cannot be edited. You can export an .xcp created in Tracker to other Vicon application software and supported third-party software.  
For example, .xcp files are required if you wish to use [Vicon Virtual System](https://help.vicon.com/space/VVS). |
| .graph | **Graph Plots **view | Graph Plots file. This file saves all currently pinned channels for future viewing.<br>If a channel is unavailable, it may not be displayed even if it was previously pinned and saved within this file. |
| .HotKeys | **Hot Keys** menu | Saves all hotkeys. Can be imported to other users or machines. |
