本文分享了两段获取磁盘空间的代码，参考下。

代码1：

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");	}}

运行结果

代码2：

public class FreeDiskSpace {	public static void main(String[] args) {		File file = new File("c:");		long totalSpace = file.getTotalSpace();		long freeSpace = file.getFreeSpace();		long usedSpace = totalSpace - freeSpace;		System.out.println("总空间大小 : " + totalSpace / 1024 / 1024 / 1024 + "G");		System.out.println("剩余空间大小 : " + freeSpace / 1024 / 1024 / 1024 + "G");		System.out.println("已用空间大小 : " + usedSpace / 1024 / 1024 / 1024 + "G");	}}

结果：
