2.2 or later seems to be written so
File f = new File (path);
if (! if.exists ()) {
file.createNewFile ();
}
If that does not work is that the virtual machine does not sdcard's size, you can then create a virtual machine, double-click you have created the virtual machine to see the information you can imagine.
