Finder Sync Extensions
Apps that synchronize local and remote files can implement a Finder Sync extension to communicate status information and expose synchronization features to the user within the Finder. For example, an app that keeps a folder in the user’s Home folder synchronized with corresponding folders on other devices might include a Finder Sync extension.
Through a Finder Sync extension, an app can:
- Display badges in the Finder to indicate the sync status of items.
- Provide custom contextual menu items that perform file and folder management tasks, like favoriting and adding password-protection.
- Provide custom toolbar buttons that perform global actions, like forcing a sync operation.
Minimize badging. To avoid cluttering Finder windows with badges, consider badging items that aren’t synced rather than every item.
