So i was installing earthbound zero on my 3ds and i made a mistake,with the mouse i took a folder and i put it inside another folder,and now when i turned on my 3ds nothing shows up except dsi games,the problem is that i don't know what was the folder that i moved i need help not only i lost all the applications i also lost a lot of saved files,also when i go to the option menu it says that i have only 4630 blocks wich is strange because my sd card is 16 gbs of memory
