Overwrite hard disk
Sir file overright pls help
If this file has been truly, actually, over-written in whole or in part -- it is gone.
If all that happened is that the pointers within the MFT has been over-written, you might get the file back via a forensic data recovery utility of your choosing. You might consider having a local data recovery person guide and walk you through the recovery process which begins with an appropriately-loaded USB or DVD boot.
