Listing computer drives and its type using Java

By Atul Rai | Last Updated: October 11, 2018 Previous       Next

In this tutorial, you will learn how to list all computer drives and its type using Java programme. In Java, you use the File.listRoots() to list all the available drives of your computer. listRoots() is a static method in File class which return the array of available filesystem roots.

File[] computerDrives = File.listRoots();

for (File drive : computerDrives) {
	System.out.println("Drive Name : " + drive);
}

To get the type of drive, you use the getSystemTypeDescription(File f) method of FileSystemView class.

File[] computerDrives = File.listRoots();
FileSystemView fsv = FileSystemView.getFileSystemView();

for (File drive : computerDrives) {
	System.out.println("Drive Name : " + drive + " Drive Type : " + fsv.getSystemTypeDescription(drive));
}

Let’s see the complete example.

package org.websparrow.file;

import java.io.File;

import javax.swing.filechooser.FileSystemView;

public class DrivesAndTypeDemo {

	public static void main(String[] args) {

		File[] computerDrives = File.listRoots();
		FileSystemView fsv = FileSystemView.getFileSystemView();

		if (computerDrives != null && computerDrives.length > 0) {

			for (File drive : computerDrives) {
				System.out.println("Drive Name : " + drive + " Drive Type : " + fsv.getSystemTypeDescription(drive));
			}
		}
	}

}

Run the above programme and you get the output as given below.

Drive Name : C:\ Drive Type : Local Disk
Drive Name : D:\ Drive Type : Local Disk
Drive Name : E:\ Drive Type : Local Disk
Drive Name : F:\ Drive Type : Local Disk
Drive Name : G:\ Drive Type : CD Drive

Note: Tested with Windows operating system.
