What do i do!!!? i extracted some files to the wrong place OK... so there was sum files that i didn't need, so i pressed Ctrl and clicked on the unwanted files, not knowing i pressed my NDS folder, CONTAINING ALL OF MY GAMES!!!! so... are they lost forever???
There is a chance they in your Recycling Bin, and haven't been deleted yet. What operating system are you using? MAC OS, or Windows?
I'm hoping you DID NOT DO ANYTHING to the card after you deleted those files (meaning, you did not add anything to it). If so, you can just use a simple recovery program such as Recuve or Undelete. Hell you can even try GETDATABACK FAT. ONLY if you didn't touch the card after you deleted the files, though.
