Files getFileStore() method in Java with Examples

getFileStore() method of java.nio.file.Files help us to return the FileStore object which represents the file store where a file is located. Once you get a reference to the FileStore you can apply fileStrore type of operation to get information of filestore.

Syntax:

public static FileStore
  getFileStore(Path path)
    throws IOException

Parameters: This method accepts a parameter path which is the path to the file to get FileStore.

Return value: This method returns the file store where the file is stored.

Exception: This method will throw following exceptions:

IOException: if an I/O error occurs
SecurityException: In the case of the default provider, and a security manager is installed, the SecurityManager.checkgetFileStore(String) method is invoked to check to getFileStore access to the file

Below programs illustrate getFileStore(Path) method:
Program 1:

// Java program to demonstrate 
// Files.getFileStore() method 
  
import java.io.IOException; 
import java.nio.file.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create object of Path 
        Path path 
            = Paths.get( 
                "D:\\Work\\Test\\file1.txt"); 
  
        // get FileStore object 
        try { 
  
            FileStore fs 
                = Files.getFileStore(path); 
  
            // print FileStore name and block size 
            System.out.println("FileStore Name: "
                               + fs.name()); 
            System.out.println("FileStore BlockSize: "
                               + fs.getBlockSize()); 
        } 
        catch (IOException e) { 
  
            // TODO Auto-generated catch block 
            e.printStackTrace(); 
        } 
    } 
} 

Output:

Program 2:

// Java program to demonstrate 
// Files.getFileStore() method 
  
import java.io.IOException; 
import java.nio.file.*; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create object of Path 
        Path path = Paths.get("C:\\data\\db"); 
  
        // get FileStore object 
        try { 
  
            FileStore fs 
                = Files.getFileStore(path); 
  
            // print FileStore details 
            System.out.println("FileStore:"
                               + fs.toString()); 
            System.out.println("FileStore Free Space: "
                               + fs.getUnallocatedSpace() 
                               + " Bytes"); 
        } 
        catch (IOException e) { 
  
            // TODO Auto-generated catch block 
            e.printStackTrace(); 
        } 
    } 
}
