## Where does OVITO store its settings?

OVITO stores the user’s settings in a platform-dependent location to preserve them across program sessions. On Windows, the information is saved in the system registry. On Linux and macOS, it is stored in a text-based configuration file under the user’s home directory. The precise storage location on your computer is displayed at the bottom of the application settings dialog.

Operating system | Storage location
--- | ---
Windows | `\HKEY_CURRENT_USER\SOFTWARE\Ovito\Ovito\`
Linux | `$HOME/.config/Ovito/Ovito.conf`
macOS | `$HOME/Library/Preferences/org.ovito.Ovito.plist`

To reset OVITO to its factory default settings, simply delete the configuration file on Linux/macOS or remove the registry branch on Windows using the Windows Registry Editor program.
