    My friend's SD card he used for his 3DS died suddenly yesterday, and he managed to recover the data on it. However due to the way Nintendo stores data on it (cryptic names and file formats)and the fact that the restoration does not recover the files within their original directories we do not know what are games, save data or something else. So I'd like to know two things:

    1. Which is the best way to check integrity on the files (since his card is corrupted);
    2. How can we identify the files (He attempted to use 3DSExplorer but I'm not sure he managed to find much, and since I don't live near him I can't actually check it either).
