java计算磁盘空间的大小，jdk1.6下通过。

import java.io.file;
 
 public class spacechecker {
     public static void main(string[] args) {
         file[] roots = file.listroots();
         for (file _file : roots) {
             system.out.println(_file.getpath());
             //system.out.println(_file.getname());
             system.out.println("free space = " + _file.getfreespace());
             system.out.println("usable space = " + _file.getusablespace());
             system.out.println("total space = " + _file.gettotalspace());
             system.out.println();
         }
         
         
         file win = new file("c:\windows");
         system.out.println(win.getpath());
         system.out.println(win.getname());
         system.out.println("free space = " + win.getfreespace());
         system.out.println("usable space = " + win.getusablespace());
         system.out.println("total space = " + win.gettotalspace());
         system.out.println();
     }
 }
运行结果：
