How do I fix a corrupted minecraft file?

I can open the minecraft launcher, but after I log in, the game doesn’t open. I have tried the solution to go to %appdata% and delete the minecraft. file, but I can’t delete the file. When I try to delete it says, "An unexpected error is keeping you from deleting the file." I have Error 0x80070570: The file or directory is corrupted and unreadable.
