FileStore getTotalSpace() method in Java with Examples
  • Last Updated : 03 Dec, 2019

The getTotalSpace() method of a FileStore class is used to return total size of the file store, in bytes. This method returns this total size as a long value.

Syntax:

public abstract long getTotalSpace()
                throws IOException

Parameters: This method accepts nothing.

Return value: This method returns the total size of the file store as a long value.

Exception: This method throws IOException if an I/O error occurs.



Below programs illustrate the getTotalSpace() method:

Program 1:




// Java program to demonstrate
// FileStore.getTotalSpace() method
  
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create the object of Path
        Path path
            = Paths.get(
                "E:\\Tutorials\\file.txt");
  
        // get FileStore object
        try {
  
            FileStore fs
                = Files.getFileStore(path);
  
            // print FileStore name and Total size
            System.out.println("FileStore Name: "
                               + fs.name());
            System.out.println("FileStore TotalSpace: "
                               + fs.getTotalSpace());
        }
        catch (IOException e) {
  
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

Output:


Program 2:




// Java program to demonstrate
// FileStore.getTotalSpace() method
  
import java.io.IOException;
import java.nio.file.FileStore;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create the object of Path
        Path path
            = Paths.get(
                "C:\\Movies\\001.txt");
  
        // get FileStore object
        try {
  
            FileStore fs
                = Files.getFileStore(path);
  
            // print FileStore name and Total size
            System.out.println("FileStore Name: "
                               + fs.name());
            System.out.println("FileStore TotalSpace: "
                               + fs.getTotalSpace());
        }
        catch (IOException e) {
  
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
