Enumerate external drives
提问by Asaf David
In java, you can use File.listRoots()to get all drives in the system.
在java中，您可以使用File.listRoots()获取系统中的所有驱动器。
I'm looking to get only the external drives, i.e. USB drives, external hard disks, optical drives, floppy, etc.
我只想获得外部驱动器，即 USB 驱动器、外部硬盘、光驱、软盘等。
Is there any way to do it in java? If not, native C++ code would be good as well. In that case, I need both Windows and Linux code.
有没有办法在java中做到这一点？如果没有，本机 C++ 代码也会很好。在这种情况下，我需要 Windows 和 Linux 代码。

To get file system info, use something like:
要获取文件系统信息，请使用以下内容：
import java.io.*;
import javax.swing.filechooser.*;
public class DriveTypeInfo
{
public static void main(String[] args)
{
System.out.println("File system roots returned by FileSystemView.getFileSystemView():");
FileSystemView fsv = FileSystemView.getFileSystemView();
File[] roots = fsv.getRoots();
for (int i = 0; i < roots.length; i++)
{
System.out.println("Root: " + roots[i]);
}
System.out.println("Home directory: " + fsv.getHomeDirectory());
System.out.println("File system roots returned by File.listRoots():");
File[] f = File.listRoots();
for (int i = 0; i < f.length; i++)
{
System.out.println("Drive: " + f[i]);
System.out.println("Display name: " + fsv.getSystemDisplayName(f[i]));
System.out.println("Is drive: " + fsv.isDrive(f[i]));
System.out.println("Is floppy: " + fsv.isFloppyDrive(f[i]));
System.out.println("Readable: " + f[i].canRead());
System.out.println("Writable: " + f[i].canWrite());
}
}
}

You could use WMI or look into
您可以使用 WMI 或查看
GetRawInputDeviceList()
GetRawInputDeviceInfo()
GetRawInputDeviceList()

This should get you started
