my version:

static private void copyFolder(File src, File dest) {
    // checks
    if(src==null || dest==null)
        return;
    if(!src.isDirectory())
        return;
    if(dest.exists()){
        if(!dest.isDirectory()){
            //System.out.println("destination not a folder " + dest);
            return;
        }
    } else {
        dest.mkdir();
    }

    File[] files = src.listFiles();
    if(files==null || files.length==0)
        return;

    for(File file: files){
        File fileDest = new File(dest, file.getName());
        //System.out.println(fileDest.getAbsolutePath());
        if(file.isDirectory()){
            copyFolder(file, fileDest);
        }else{
            if(fileDest.exists())
                continue;

            try {
                Files.copy(file.toPath(), fileDest.toPath());
            } catch (IOException e) {
                //e.printStackTrace();
            }
        }
    }
}
