The picture recovery process can only be successful if the media where the pictures were stored is not used again
. Once new pictures are taken on an old memory card or cell phone, the old pictures that had been deleted are written over by the new files. Make sure that any lost photos or data are recovered before the media is reused for any reason. If the camera wants to reformat a drive or memory disk it is possible that the reformatting will also cause the data to be damaged and lost forever. Data recovery software can only recapture images that have not been damaged or written over.
