emeraldknytt:When files are deleted, they are never truly erazed from memory, every device OS works with the same storage option locally. With a proper magnetizing device, you can always retrieve deleted files. The binary codes are only hashed in memory and the pointer to them is no longer known, i won't mind you reading up on this. 1 Like |

They don't go anywhere, they say on the phone until you overwrite them with other stuff. |

rozay12345:I still don't quite agree with you. You see, once a file is deleted without being backed up or comprypted (compressed+encrypted in respect to a particular software or OS) such file is GONE!. I don't mind you giving me an instance that supports your claim (something incoherent to my post. we learn everyday) |

emeraldknytt:Let me explain to you the way this works but before i do, what is your expertise in technology?, here is the way memory works, it is just like an excel file, a key and a value, the key is the pointer to the memory allocation in the disk, when you delete a file, that pointer which points to the memory location is hashed, in layman terms the pointer is forgotten, if the pointer name was 00000000, it changes to 01010101 in such a way that the pointer forgets the location, with a strong magnetic energy, you can repoint this deleted memory back.What i am informing you about is undergoing serious research but it is very costly to do: please read this article:The first method is to do with variations in magnetic flux. When data is written to disk, the resultant magnetic flux depends mostly on the value written. However, the flux is also provided with a tiny contribution from the overwritten data. So, if you replace the normal read electronics that decide whether a bit is a 1 or a 0 with circuitry that can extract the analogue value from the head, subtracting the known contribution of the most recently written data should make it possible to determine what value was in place before it. This method of extracting overwritten data is commonly reported and academic papers have been written on the subject, but we've been unable to find any organisation that claims to have done it successfully. The problem is that the signal to the previously written data is so small that it effectively gets lost in the random electrical fluctuations commonly referred to as noise. However, Western Digital's Gerardo Bertero – while questioning whether the technique is really a practical proposition – did suggest one possible solution. By reading each bit thousands if not millions of times and averaging all those signals, electrical noise, being random in nature, would average out to zero – whereas the genuine signal would build up and become visible. The snag is that this would be hugely time-consuming and costly – which is why nobody offers such a service. 2 Likes |

In simple terms, the files remains on the hard-drive. The pointer which leads to that same memory location gets reassigned. That's all. Other files can overwrite/merge with the file when assigned to the same memory location causing a mess during data recovery. 2 Likes |

Re: Where Do Things Deleted On Phones Go To? by chupcake(m): 11:56am On Nov 18, 2017 |
Mckandre: exactly. they stay on your phone until it is overwritten and even when they get overwritten, point a good recovery software at it and you might be able to recover it unless it had been written over multiple times |

Pushas: Pls dont b too angry wt NL members; we love to be funny, sarcastic or outright annoying sometimes. If Nairaland is always SERIOUS, some folks like us that love to simply read threads,& all forms of comments would have deleted the App long ago. So, after a hard days job, u dont need to see everything in a serious outlook to life. That's when d comedian commentators, sarcastic mentions & all so-called stupid comments make our day worth it.
