As you can image,if I gonna learn the courses course-to-course.I gonna find it difficult and boring to find each them,and the sort type is not what we want. So I have to rename the file as simple as possible.

Here is just  a segment code that demonstates how to use the  File.renameTo(File).

public static void main(String[] args) {
        String path = "H:\\Java\\JavaSE\\";
        File root = new File(path);
        String oriName = "";
        String newName = "";
        String toClip = "[北京圣思园Java培训教学视频]Java.SE.";
        for (String f : root.list()) {
            File fSub = new File(path + f); //File to be rename(Must append from the root path).
            if (!fSub.isFile())    //Only operate File.
                continue;
            if (fSub.getName().startsWith(toClip)) {
                oriName =fSub.getName();
                newName = oriName.substring(toClip.length());
                File fSubNew = new File(path + newName);    //The target File.
                if(fSub.renameTo(fSubNew))
                    System.out.println(fSub.getAbsolutePath() + " rename successfully");
                else 
                    System.out.println(fSub.getAbsolutePath() + " rename failed");
            }
        }
    }
