This section includes the Save extension to file button, which checks the difference between the current filled-in values and the loaded cluster and saves the difference to an XML file.
The Matter Cluster Editor app automatically compares your current cluster with the originally loaded cluster and saves only the differences as an extension file. This means the following:
- Only newly added elements are included in the extension.
- Modified elements are included with their new values.
- Unchanged elements are not included in the extension.
If there is no difference, the tool shows a notification indicating that there is no data to create a cluster extension.
