This is my first time posting on this forum, so please tell me if this is formatted wrong.
While using the original microSD card that came with the 3ds, I transferred my old 3ds XL data with the Low Capacity microSD transfer. After the transfer finished, I only had 3000 blocks left on the card and no software titles available to delete. I then connected the microSD with the microSD card Management option in Data Management and found a 2.54 GB that seems to be taking up all the space.
The file was under title\00040000\00126300\content. What can I do to remove this, and if it is not removable, should I just reformat the microSD?
