    Here's another simplier one from: http://javaalmanac.com/egs/java.io/DeleteDir.html

        // Deletes all files and subdirectories under dir.
        // Returns true if all deletions were successful.
        // If a deletion fails, the method stops attempting to delete and returns false.
        public static boolean deleteDir(File dir) {
            if (dir.isDirectory()) {
                String[] children = dir.list();
                for (int i=0; i<children.length; i++) {
                    boolean success = deleteDir(new File(dir, children[i]));
                    if (!success) {
                        return false;
                    }
                }
            }
        
            // The directory is now empty so delete it
            return dir.delete();
        }

    first I would thank you for your help.
    I apreciated your code examples.
    But as I am a newbie, I wonder what would happens if I call a File object constructor with a path name that match with a file wich already existing.
    Would the constructor overwrite it? Or just launch an IO ex?
    Thanks again.
