Java - File getTotalSpace() Method
Description
The Java File getTotalSpace() method returns the size of the partition named by this abstract pathname.
Declaration
Following is the declaration for java.io.File.getTotalSpace() method −
public long getTotalSpace()
Parameters
NA
Return Value
The method returns the size, in bytes, of the partition.
Exception
SecurityException − If a security manager has been installed and it denies RuntimePermission("getFileSystemAttributes") or its SecurityManager.checkRead(String) method denies read access to the file.
Example 1
The following example shows the usage of Java File getTotalSpace() method. We've created a File reference. Then we're creating a File Object using F:/test directory which is present in the provided location. Now using getTotalSpace() method, we're getting the total space in the partition.
package com.tutorialspoint; import java.io.File; public class FileDemo { public static void main(String[] args) { File f = null; long v; boolean bool = false; try { // create new file f = new File("F:\\test.txt"); // get number of allocated bytes v = f.getTotalSpace(); // true if the file path exists bool = f.exists(); // if file exists if(bool) { // prints System.out.print("number of allocated bytes: "+v); } } catch(Exception e) { // if any error occurs e.printStackTrace(); } } }
Output
Let us compile and run the above program, this will produce the following result −
number of allocated bytes: 177142231040
Example 2
The following example shows the usage of Java File getTotalSpace() method. We've created a File reference. Then we're creating a File Object using C:/test directory which is present in the provided location. Now using getTotalSpace() method, we're getting the allocated bytes in the partition.
package com.tutorialspoint; import java.io.File; public class FileDemo { public static void main(String[] args) { File f = null; long v; boolean bool = false; try { // create new file f = new File("C:\\test"); // get number of allocated bytes v = f.getTotalSpace(); // true if the file path exists bool = f.exists(); // if file exists if(bool) { // prints System.out.print("number of allocated bytes: "+v); } } catch(Exception e) { // if any error occurs e.printStackTrace(); } } }
Output
Let us compile and run the above program, this will produce the following result −
number of allocated bytes: 62230548480
