Finding the hard disk space information using Java SE 6

public class PrasTest
{
public static void main(String[] args)
{
File file = new File(“c:\\”);

//Returns the size of the named partition
System.out.println(file.getTotalSpace());

//Returns the number of unallocated bytes in the partition
System.out.println(file.getFreeSpace());

//Returns the number of bytes available to this virtual machine on the partition
System.out.println(file.getUsableSpace());
}
}

Here, we need to keep in mind that the file object on which we call the methods must represent the disk partition/volume, otherwise we may not get the expected results.
