around the start of 2025, i started being unable to put files on my 3ds because ctgp7 took a bunch of space on my microsd card. i measured it recently and there was only around 4gb on it.
well today my dad found a microsd card lying around, and weirdly enough, it was completely empty, and already formatted to fat32. i quickly moved my files to the new microsd card, and now i can benefit from all this huge bunch of space!!
