You will not be able to see the files on the Razr because it is an unrooted device. The files stored in File.DirInternal are private to the application. If you want to see those files, store them in File.DirRootExternal or File.DirDefaultExternal. I have a Razr and I usually use the RootExternal or a folder created in it. You can access it via any file manager. If you store them in RootExternal, go to you internal phone storage via your file explorer, you will see the files unless you created folder, then they would be there.
If you use DefaultExternal, you can see them here: Android/data/packagename/files folder.
