Lists all file names under the directory---Listfiles.java

File name/*
* Created on 2004-12-9
* I haven't found a common software that has this feature, so I wrote this class
* You can list files in the CD in TXT file, easy to find in the future, or print out.
* Do not need to find a disc in a CD-ROM to find a CD, slow and loss of optical drive.
* Of course, you can also select a directory to record all the file names under the directory.
