What happens if my world save is "corrupt and unreadable"; It is unaccessable!?

Question

I was playing Minecraft When the laptop ran out of battery. I was devastated until I remembered that there was a way to recover my world. At first, I tried to access my world through roaming (%appdata%) and I found my saves. My world, ("Survival of the Fittest") was there but when I tried to access it, it said, "The file or directory is corrupted and unreadable." I figured out I couldn't fix it from their without using backups. HELP!
