Where Exactly Do Deleted Files Go?
It is estimated that 23 wonders of both the ancient and modern world have either being lost, destroyed or ruined(source), and while it is also estimated that about 75% of all the original silent films ever made or produced have been deleted from history(source) just like that instagram or snapchat selfie you took but deleted as you deemed it unfit to be shared with others on social media platforms. But what if I told you that very picture wasn't actually "deleted" and can be fully recovered with the right tools and determination! Or here's something much better to think and ponder about; we regularly delete files from our computers all the time for several reasons, be it to free up much needed memory space or simply just to remove junk from our computers, and when we do actually delete them they are moved to a kind of jail or purgatory called the recycle bin, where it now fully awaits it's final judgement be it a bail grant or permanent deletion.
Now the question is, what do you really think happens when the recycle bin is emptied thus disposing off the junk it contains? Does the computer simply just "take out the trash?" or does it simply just forget they ever existed in the first place?
Come to think of it, if it does indeed take out the trash, won't the continuous trash accumulate to a significant amount thus occupying much needed space "somewhere else"? These and many more are some of the ridiculous questions which I once did ask myself. These questions came about especially after reading somewhere that AVAST was somehow able to use "data forensic analysis" to recover and pull off more than 40,000 deleted texts, pictures and emails from 20 previously owned android phones it purchased from e-bay. And just in case you were wondering, of course they did find over 250 male nude supposedly "deleted" photos along with roughly 750 for women both scantily clad and fully undressed(source). The report even goes further to say that one guy who previously owned one of the phones had a serious affinity for anime porn!(Haha, what a crazy world we live in!). So this really begs the question; how can I fully and convincingly know I have completely or permanently deleted files from my phone or computer without them being ever recovered again? Well, the answer and truth is you don't. But then again, if there's always that chance that my deleted files like my private pictures, texts and emails can be fully recovered and re-posted by my enemies on facebook, twitter and instagram for public viewing, what then is the point of deleting them in the first place? Well, again I guess that's a chance we'll all have to take and something we'll have to live with if it eventually does happen, although maybe you should really just stop taking and sending nudes. At least that way you'll have some much needed inner peace and absolutely nothing of that nature to worry about. But what really happens when a file is permanently deleted? Let's see for ourselves.
What Really Happens When A file Is Permanently Deleted?
So let's say you've deleted a couple of files from your computer and they are now in your recycle bin, and then you head over there as well and permanently delete them from the bin. What exactly happens to them? Well, the truth is that NOTHING actually does happen to them as they are not deleted per se. This is because the physical space inhabited by the file isn't "emptied" but instead it is marked as "emptied" therefore making that "space" available for newer data to be stored there if need be. Your files can be likened to a tenant living in your house(disk space) thus making you a landlord(the computer owner), if for any reason the tenant misbehaves and you evict him from your house, he vacates the space but the house or physical building although now vacant remains intact, thus becoming empty and available for newer tenants(newer data) to rent the space and move in.
Therefore when a file is permanently deleted, the computer simply removes the "pointers" or "reference" which once or previously referenced and pointed to the part on the hard drive where the file was stored, and thus newer files can be stored on that very space formerly reserved for the just deleted file. So, in summary the file is still there on the hard drive but is now unreadable by the computer, which is the primary reason why data recovery processes can be initiated and carried out effectively by data analysts and specialists who make use of special data recovery tools and software to retrieve such supposedly "deleted" data.
So in essence, to completely delete a file you would have to literally pulverize that very file and burn it completely to ashes thus ensuring that there are no remains or left overs of the file simply by completely overwriting that very file with new data. And although many persons may do between one to 40 overwrites which is crazy and way over the top, it still may not be enough especially for hard drives with "BAD SECTORS" which are parts of a drive that devices cannot access and are unwriteable due to possible physical damage to the drive's components.
With these and many more facts and reasons just considered, it becomes really obvious that to permanently delete any file or data you may need to physically destroy the device housing it which is totally insane, although that's the only way to totally and completely guarantee that your files will never ever see the light of day. But what if you took a bad picture with your phone, deleted it and then smashed the phone to the ground, and then you picked up the pieces and threw them into a blast furnace but yet somehow you're still worried that someone might be able to use some weird and crazy means to recover and see the picture someday? Well, you need not worry anymore because very soon, in approximately 5.4 billion years the sun will become the ultimate shredder and destroyer, as it will by then become a burning red giant large enough to swallow earth whole along with all your unwanted files and data you so desperately want to destroy and DELETE!

As a computer engineer by study, I enjoyed this piece.. I think this presents a problem that needs to be solved..
I couldn't agree more bro. Thanks a lot for stopping by.
Wow this is awesome 😍...
Thanks alot for stopping by brother.
I actually starred the post last night so I could read it today and I imagined if a deleted file ,a broken link in other words can be restored it means there are software that actually works on broken links to restore them.
Please in your next post can you help us do the findings? I'm interested
Thanks a lot for making out time to read this, it really does mean a whole lot to me. Thanks once again + I'm not really an expert or professional when it comes to data retrieval so I kind of lack the experience and know-how in that very field and area at the moment...but perhaps maybe in the future I may write something at least close to that if not exactly that.
