[hamad-gamal]

enable multi-file selection, we'll need to implement the following steps:

1. Add a Button or Menu Action: This will serve as the trigger for the user to initiate the multi-file selection.
2. Open a Multi-File Selection Dialog: When the user clicks the button or menu action, a file selection dialog will open, allowing the user to select multiple files.
3. Handle Selected Files: Once the user selects files and confirms, we'll need to process or handle these files based on the desired functionality (e.g., copying, moving, etc.).

Given the content of files.py, I'll provide code snippets to achieve the above steps:

1. Add a Button or Menu Action:

You can add a button to the toolbar or a menu action. For simplicity, let's add a menu action:

file_selection_action = QAction('Select Multiple Files', self)
file_selection_action.triggered.connect(self.select_multiple_files)
self.file_menu.addAction(file_selection_action)

2. Open a Multi-File Selection Dialog:

We'll create a method called select_multiple_files:

def select_multiple_files(self):
    file_names, _ = QFileDialog.getOpenFileNames(self, 'Select Files')
    if file_names:
        self.handle_selected_files(file_names)

Here, QFileDialog.getOpenFileNames returns a tuple where the first element is a list of selected file paths.

3. Handle Selected Files:

Finally, implement the handle_selected_files method to process the selected files:

def handle_selected_files(self, file_names: list):
    # Implement your logic here
    # For now, let's just print the selected files
    print("Selected files:", file_names)

Integrating these snippets into files.py will enable multi-file selection in the GUI.

please check if this working or not
