Finder Sync Extensions
Apps that sync local and remote files should include a Finder Sync extension. For example, if your app syncs a folder within the user's Home folder, the Finder Sync extension can relay status information to the user within the Finder.
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.
