Discussion: In this section, the file table is being shown. After successful operation, the list of preferences
will be shown by calling of main function Project.main(arr).
Display the free space bitmap
Code:
void DiskSpaceDetails()
{
System.out.println("Welcome to Free Space Display Section");
File file = new File("c:");
long ts = file.getTotalSpace();
long us = file.getUsableSpace();
long fs = file.getFreeSpace();
System.out.println("Showing Disc Space Map");
System.out.println(Long.toBinaryString(ts));
System.out.println(Long.toBinaryString(us));
System.out.println(Long.toBinaryString(fs));
String arr[]={};
Project.main(arr);

Discussion: In this section, disc space bitmap will be shown in binary. This is actually showing the space
block of a disc.After successful operation, the list of preferences will be shown by calling of main
function Project.main(arr).
Display a disk block
Code:
void DiscBlock()
{
System.out.println("Welcome to Display Disc Block Section");
System.out.println("File system roots returned by
FileSystemView.getFileSystemView():");
FileSystemView fv = FileSystemView.getFileSystemView();
File[] rts = fv.getRoots();
for (int i = 0; i < rts.length; i++)
{
System.out.println("Root: " + rts[i]);
}
System.out.println("Directory: " + fv.getHomeDirectory());
System.out.println("System returns:");
File[] fl = File.listRoots();
for (int i = 0; i < fl.length; i++)
{
System.out.println("Drive: " + fl[i]);
