Please any suggestion how do i can refresh my file/folder badge icon (Like Dropbox)

It's simple, First establish an Inter Process communication between your app and your extension. In an IPC, your app acts as a client and extension act as a server. Now you know the state of a specific file, so just send the file path and status to the extension through IPC, Once extension receives the path and status, then call the Finder Sync controller's setBadgeIdentifier:forURL: method to set the appropriate badge.
