        FileObject fo = VFS.getManager().resolveFile(remoteFilePath, opts);

        System.out.println(fo.exists());

        //fo.createFile();

    }
}

This is a program to read a file from the remote machine and store it in our local machine as file E:/Suman.txt.

Take care while writing the file path means instead of : we have to replace it with $ symbol, e.g.:
D:\Suman\Boorla\kpl.txt is wrong,
D$\\Suman\\Boorla\\kpl.txt is right.

In the above program, you have to change the domain name, username, password and file path of the remote machine.
To work with the above program we need to add the following jar files int the classpath.

commons-vfs.jar
commons-logging.jar
