A very cheesy trick but one that can save a lot of space is to remove the covers from the device where they are housed once they have appeared on the screen of our wiiflows. They no longer appear because they are hosted there, they appear because they are already in the wiiflow/cache route. I'm sure many people already know it, but here it is stated for those who don't have much space on their SD or hard drives. Once the file is created in the cache, it can be renamed and appear again.
