Get free disk space in Java example

With this tutorial we are going to see how to use the File class in order to get the size of certain disk partitions in your file system.

You can use:

  • getTotalSpace() to get the total capacity of the disk partition you want.
  • getFreeSpace() to get the free space of the disk partition.
  • getUsableSpace() to get the usable space in the disk partition.

Let’s take a look at the code:
 
 

package com.javacodegeeks.java.core;

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");
	}
}

Output:

**** Sizes in Mega Bytes ****

Total C partition size : 610376 MB
Usable Space : 107098 MB
Free Space : 107098 MB

**** Sizes in Giga Bytes ****

Total C partition size : 596 GB
Usable Space : 104 GB
Free Space : 104 GB
