Use the File methods; "list()" to get a listing "isDirectory()" to
recursively check through your filesystem starting at the root of the
drive you wish to check.
import java.io.File;
import java.util.ArrayList;
public class DirLister {
private static ArrayList dirs = new ArrayList();
public static void listDirs(File dir) {
String[] list = dir.list();
for (int i=0; i<list.length; i++) {
File f = new File(dir, list[i]);
if ((f.canRead()) && f.isDirectory()) {
dirs.add(f.getAbsolutePath());
listDirs(f);
}
}
}
public static void main(String[] args) {
File dir = new File("c:" + File.separator); // or whatever
listDirs(dir);
// do something with "dirs"
}
}
You should have been able to Google for a solution exactly like this.

No idea what you mean.
