   I asked before, but I ask again.
   
   My rPI0 crash and the OS corrupted so I reinstall but forgot to back up a C program I made.
   
   What can I do to recovery it?
   
   It's a small text file and the card is 8GB in size.

   There's a chance you might be able to recover it with testdisk or a similar program. AFAIK SD cards don't do anything like TRIM or garbage collection so if it's not overwritten by the OS files then it should still be there.
