A Java-written batch rename file applet

Today learned the Java file operation, and then took the interest, wrote a can batch processing file naming small program, small program also has some imperfect place, but wins in interesting. For example, you can quickly change the files you don't want others to see ... Personal use, resulting in the consequences of data loss at your own risk.

If you have time, you can write a small program to clean up the garbage file ~ ~ or some files can not be deleted directly, used for brute force deletion.
