    Hey guys, I have a big problem.
    I wanted to optimize the sd-card with the help of the datawriter , he made a backup which is 12gb.
    But when i want to restore the games+save data and click on "restore games", he tries to read the backup data and shows me an error :
    System.IO.IOException:The process cannot access the file 'D:\3DS\Disk Writer\temp.dwt' because it is being used by another process.
    What am I doing wrong? I really don't want to lose every game + save data.
    Please help me!
