Hi Friend,

Try the following code:

import java.io.*;
class Listing {
String st = "";
File file;
File f;
public Listing(File f) {
this.file = f;
this.f = f;
}
public void displayFiles() {
findFiles(f);
}
public void findFiles(File f){
if (f.isDirectory()){
st = getFiles(f);
System.out.println(st + f.getName());
File files[] = f.listFiles();
for(File ff : files){
findFiles(ff);
}
}else if (f.isFile()){
System.out.println(st + " " + f.getName()+" Size is: "+f.length());
}
}
private String getFiles(File f) {
String originalPath = file.getAbsolutePath();
String path = f.getAbsolutePath();
String subString = path.substring(originalPath.length(), path.length());
String st = "";
for(int index=0; index<subString.length(); index ++){
char ch = subString.charAt(index);
if (ch == File.separatorChar){
st = st + " ";
}
}
return st;
}
}
public class ListAllFiles {
public static void main(String[] args) {
String p = "C:\\" ;
Listing list = new Listing(new File(p));
list.displayFiles();
}
}

Thanks
