Flick up on the app to get the arrange apps option. That will put it into edit mode or something like that. Do a two finger sig sag gesture and that will close the folder, then go to the folder where you want the app to be and flick up or down to go through your options. There's things like put the app beside the folder or in the folder. Select what you want, then hit the home button to put it out of edit mode and your done.
