On one of my PlayStation Vita SD cards, I noticed something in Content Manager:
There is an Other section. This section has two parts-System Use and Download Use.
While Download Use is only taking up 128KB, this "System Use" is taking up 2532MB (~2.5GB).
This makes me really mad, seeing as this SD card is only 8GB, and I need to fit Hatsune Miku Project DIVA f on here (if it's even possible), along with all my music. At the moment, I only have about 69 songs (365MB) taking up any crucial space (referring to how I plan to delete anything else taking up space), but this list WILL grow in the future, and I'd like to have the space for then.
So, with all this being said, what even is the "System Use" thing, and how do I stop it from taking up space?
