    Are you using the correct method(s) for copying the contents of a directory?
    What does the API doc for the copy() method say?
    If you don't understand my answer, don't ignore it, ask a question.

    The API doc says:
    This method (copy) can be used with the walkFileTree method to copy a directory and all entries in the directory,

    There is a link there to follow.

    Directories can be copied. However, files inside the directory are not copied, so the new directory is empty even when the original directory contains files.

    I assume that is from the API doc for the copy() method. Is that right?

    the source folder like
    if path1 is path1/new1/copy
    and path2 is path2/new2/
    and i am moving/copy Path1 to path2 then copy should be copied/moved to new2 folder, but the new2 folder is empty,
    however if i move/copy file like this its perfectly working


    import java.io.IOException;
    import java.nio.file.Files;
    import java.nio.file.Path;
    import java.nio.file.Paths;
    import static java.nio.file.StandardCopyOption.*;
     
     
    public class Main {
     
    	public static void main(String[] args) throws IOException {
     
    		Path p1 = Paths.get("path1\\news.txt");
    		Path p2 = Paths.get("path2\\new\\new.txt");
     
    		//System.out.format("%s%n", Files.isReadable(p2));
    		//System.out.format("%s%n", Files.size(p2));
    //		System.err.format("error");
    		//System.out.format("getName()%s%n", p1.getName(0));
    		//System.out.format("FileName()%s%n", p1.getFileName());
    		//System.out.format(".toUri()%s%n", p1.getNameCount());
     
    		Files.copy(p2, p1, REPLACE_EXISTING);
    		//System.out.println(p2.getFileName() + " has been successfully copied to " + (p1.toAbsolutePath()) );
     
    	}

    What happens when you execute the code posted in post#1? Does it copy the directory?

    To see how to copy the contents of a directory you need to read what I referred to in post#6.
