But when adding files more than 1000 to the ListBox cause No Response issue for 15secs.

    If you are not running your code asynchronously that would cause no response to the user interface.

    The following works but does not directly plug in and work, you need to examine the code, adapt to your needs. Currently will traverse a directory structure and keep the user interface responsive. Needs additional code to actual interact with files.

    Find code in this class project.

    Sample to call the code is done in a Windows Form app but can be done in WPF also. Pay attention to the CancellationTokenSource used.
