Last Updated :
03 Dec, 2019
The getUsableSpace() method of a FileStore class is used to return the number of bytes available to this Java virtual machine on the file store. This method is useful to check free space. This method returns the available usable space as a long value.
Syntax:
public abstract long getUsableSpace()
throws IOException
Parameters: This method accepts nothing.
Return value: This method returns the available usable space as a long value.
Exception: This method throws IOException if an I/O error occurs.
Below programs illustrate the getUsableSpace() method:
Program 1:
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)
{
Path path
= Paths.get(
"E:\\Tutorials\\file.txt" );
try {
FileStore fs
= Files.getFileStore(path);
System.out.println( "FileStore Name: "
+ fs.name());
long bytes = fs.getUsableSpace();
long sizeInGB = bytes / ( 1024 * 1024 );
System.out.println( "Usable Space: "
+ sizeInGB + " MB" );
}
catch (IOException e) {
e.printStackTrace();
}
}
}

Output:
Program 2:
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)
{
Path path
= Paths.get(
"C:\\Movies\\001.txt" );
try {
FileStore fs
= Files.getFileStore(path);
System.out.println( "FileStore Name: "
+ fs.name());
long bytes = fs.getUsableSpace();
long sizeInGB = bytes / ( 1024 );
System.out.println( "Usable Space: "
+ sizeInGB + " KB" );
}
catch (IOException e) {
e.printStackTrace();
}
}
}
