取得硬盘剩余空间的Java代码

import java.io.File;

public class DiskSpaceDetail {

public static void main(String[] args) {

File diskPartition = new File("C:");

long totalCapacity = diskPartition.getTotalSpace();

long freePartitionSpace = diskPartition.getFreeSpace();
long usablePatitionSpace = diskPartition.getUsableSpace();

System.out.println("**** Sizes in Mega Bytes ****\n");

System.out.println("Total C partition size : " + totalCapacity / (1024*1024) + " MB");
System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024) + " MB");
System.out.println("Free Space : " + freePartitionSpace / (1024 *1024) + " MB");

System.out.println("\n**** Sizes in Giga Bytes ****\n");

System.out.println("Total C partition size : " + totalCapacity / (1024*1024*1024) + " GB");
System.out.println("Usable Space : " + usablePatitionSpace / (1024 *1024*1024) + " GB");
System.out.println("Free Space : " + freePartitionSpace / (1024 *1024*1024) + " GB");
