JDK 1.6 provides few new methods ? getTotalSpace(), getUsableSpace() and getFreeSpace(), bundled with java.io.File. These methods provides essential information regarding disk space.

getFreeSpace() method- This method returns the number of unallocated bytes in the disc.

Here is the code:

import java.io.File;

public class FileFreeSpace {
	public static void main(String[] args) {
		File file = new File("C:");
		long value = file.getFreeSpace();
		System.out.println("Free space= " + value + " bytes");
	}
