Hi. Not too long ago I had purchased a refurbished Wii U 32 GB system, but I haven't really had a need for a large amount of storage space until now.
I bought Super Smash Brothers off of the E-Shop, however I only have 12 gigabytes of space in my system memory, even though I'm supposed to have around 25 gigabytes after all of the necessary stuff.
I feel like I'm being dumb, but I'm having difficulty finding anyone with this same problem so I can't find a solution. What's taking up all of that memory and how do I go about deleting it? I already checked data management, and I'm a bit lost.
