    override func performDragOperation(_ sender: NSDraggingInfo) -> Bool {
        let fetched = sender.draggingPasteboard.readObjects(forClasses:  [NSURL.self], options: nil)?
            .map({ (argv) -> String? in
                guard let url = argv as? URL else{
                    return nil
                }
                return url.path
            }).compactMap({$0})

        guard let result = fetched else{
            return false
        }
        // handle the result
        print(result)
