Getting the default root directory in Java

Question

I'm making a basic file browser, and want to know how to get the default root directory. I know that java.io.File.listRoots() gives all the roots (for me it's A:\, C:\, D:\, E:\, F:\, G:\, H:\, I:\, L:\ T:\, U:\, X:\, Y:\, Z:\), but I want the one the user uses primarily (i.e. the one with the Operating system on it) so I know from where to start the browsing.

Answer 1

Not sure if this is of any help, but you could try:

import javax.swing.filechooser.*;

FileSystemView.getFileSystemView().getRoots()[0];

or

FileSystemView.getFileSystemView().getHomeDirectory();

or

System.getProperty("user.dir");

For the last snippet, you could get the root directory by navigating upward using getParent() until null is returned.
