Is there a framework in macOS that I can use to programmatically copy files and get a progress bar the same as copying files from Finder?
Alternatively, I can do the copy using cp or filesystem APIs and use NSProgressIndicator to implement the progress bar.

Answer 1

You can use copyFile.
Here is example of copyfile with Progress Callback.

Answer 2

I had the same problem, but I needed it in swift.
But great Project Parag it really help me!
Thats my Copy Function.
func createCopy(of:URL, to:URL,skip:Bool) throws {
if !skip {
if FileManager.default.fileExists(atPath: to.path) {
print("\n\n did not copy \n\(of.lastPathComponent.utf8CString) \nto \n\(to.path)\n\n")
return
}
}
//open window
let copyStoryboard = NSStoryboard.init(name: "copyProgessWindow", bundle: nil)
self.progressWindowConrtoller = copyStoryboard.instantiateController(withIdentifier: "CopyProgressWindow") as! NSWindowController
let application = NSApplication.shared
//set Up view
let viewController = self.progressWindowConrtoller!.contentViewController as! CopyViewController
viewController.path_copyFrom.url = of
viewController.path_copyTo.url = to
DispatchQueue.global(qos: .userInteractive).async{
do{
let bufferSize:Int = 64*1024;
var buffer = [Int32](repeating: 0, count: Int(bufferSize))
let open_source = open(of.path, O_RDONLY);
let open_target = open(to.path, O_RDWR | O_CREAT | O_TRUNC, S_IWUSR | S_IRUSR);
let attrSource = try FileManager.default.attributesOfItem(atPath: of.path)
let sourceFileSize = attrSource[FileAttributeKey.size] as! UInt64
var bytes_read = 0;
bytes_read = read(open_source, &buffer, bufferSize);
while(bytes_read > 0){
write(open_target, &buffer, bufferSize);
if FileManager.default.fileExists(atPath: to.path) {
let attrTarget = try FileManager.default.attributesOfItem(atPath: to.path)
let targetFileSize = attrTarget[FileAttributeKey.size] as! UInt64
DispatchQueue.main.async {
viewController.progressbar_progBar.doubleValue = self.progressProcent
}
self.progressProcent = Double(targetFileSize)/Double(sourceFileSize)
print(self.progressProcent)
}
bytes_read = read(open_source, &buffer, bufferSize);
}
// copy is done, or an error occurred
close(open_source);
close(open_target);
sleep(2)
DispatchQueue.main.async {
application.abortModal()
self.progressWindowConrtoller!.close()
}
}
catch{
print(error)
}
}
application.runModal(for: self.progressWindowConrtoller!.window!)
}
I have a storyboard file called 'copyProgessWindow.storyboard' and important is the storyboardID set to 'CopyProgressWindow'. and it looks like this:
storyboardCopyProgress
Thats my ViewController for the view you see:
class CopyViewController: NSViewController {
#IBOutlet weak var path_copyFrom: NSPathControl!
#IBOutlet weak var path_copyTo: NSPathControl!
#IBOutlet weak var label_remaindingTime: NSTextField!
#IBOutlet weak var progressbar_progBar: NSProgressIndicator!
override func viewDidLoad() {
super.viewDidLoad()
}
}
