    Where is the indexing/directory data stored, how is that deleted, does it also still exist after deleting?

    almost scary how we even managed to come up with this way of storing information.

    regardless thx for the info, got go through a couple of step next time i say goodby to my pc.
    trash it badly.
    burn it
    find some substance that mess up those layers.
    bury it (better be sure....)

    Depends on the formatting type. A quick format wipes the file allocation table or FAT. A full format wipes the FAT and writes 0's on the entire disk.

    So it doesn't deletes the data ,it simply ignores that data until it's full of space and needs that ignored space and then it alters the magnets
    However, any information that once existed on internet can never be deleted, until any situation like dr.stone arrives where almost every human creations decompose

    If you want to really delete it, you need to overwrite it. Delete, then download something on it. In particle this probably means that you need to fill the whole drive to be sure.

    If I recall, only DOS or windows editions had an undelete button or command. You basically, only if you did it before the file was overridden, could undelete a file.

    That's why I fully format my discarded drives if possible, then physically destroys them before they go to the waste bin in order to make sure.

    There's a reason why a quick format takes like 5 seconds to complete compared to a full format that can take up to 5 hours if it's a big drive.

    Easier way to think of it. A hard drive is like a wasp nest. Every chamber is a slot for information fragments. When a file is saved, its stored in these cells. The file is split into thousands of tiny pieces to make it faster to load. When you "delete" a file, it merely toggles a YES/NO setting to let the machine know all the cells that made up that file are available to be OVERWRITTEN. Everything still remains. The only way you know a file is 100% gone is by OVERWRITING those available cells already containing info. This is how they can solve crimes even with a few shreds of a damning document/photo/etc. I remember long ago in the early/mid 90s when the net was more or less a huge pile of unchecked forums loaded with illicit things (yeah, Ive stumbled on stuff I didnt want to), Id see these CDs that were supposed to help you eliminate digital data by loading your system to the brim with GARBAGE FILES which would overwrite everything but the main system files, then "delete" all the junk. The junk would remain but whatever it buried would be gone. Your system would be "flushed" and fully available for re-writing. (This is also what DEFRAGMENTATION is all about. As you write and re-write files to the same cells, things get MESSY, cells are scattered more and more, and the machine runs slower because of it. Defragging more or less repositions all the cells into a nice neat cluster instead of the jagged strip of lines you see at the start of said process.)

    A proper data recovery lab has black magic tools and tricks beyond a DIY software. One way involves reading the edge of the track for a trace of previous data. Sometimes you get lucky.

    But, it doesn’t make sense?? when I remove files on my system, my total storage percent decreases... So, If this is true, your removed files actually still inside in your disk?? Right? So.. once you wrote bytes on your disk, That’s impossible to remove it "totally"??? I still couldn't understand! Could someone help me to get the point?  how my remain storage increased in that case?? ?

    In the mid 2000s police suspected a man had been to some very bad corners of the internet and had downloaded many illegal things while he was there.
    According to one of the man's ex-gfs he had an entire hard drive filled with.... Lets call it... Pizza.
    Normally it wouldn't be hard to get a search warrant to find the drive. But the ex was not found credible because according to her own testimony they had a messy breakup. The judge wasn't convinced that she wasn't just trying to get him back. So no warrant.
    So she faked going back to him. Pretending to reconcile the relationship. Then she asked him if he had a HDD he didn't need anymore. He gave her an old formatted drive.
    She took it to the cops and they found a mountain of pizza on it after they did forensic data recovery.
    His lawyer would construct a defense stating that the ex had set him up. That the drive in question was never in his possession and she had lied to the police.
    The man would be vindicated when it would come out at trial that the HDD contained recovered data that pointed to it being her drive, not his. Data she had tried to delete before filling it with pizza she had downloaded to set him up.
    He was found not guilty.

    I believe I got around this by writing 0x00 or even 0x71 all over the file in c++ programs. Plus bypassing optimization in case it helps. 0x71 appears as a million letter q's if you open it as text.

    TLDW: Basically "deleting" an item just marks the item to be overwritten. The "storage space" of an item is more about how much storage is locked or unlocked for overwriting purposes

    This is only true with with spinning hard drives most hard drives or ssds now it does work similar but you can't really recover it in the same way as a spinning disk and formatting a hard drive does actually write ones and zeros two the entire hard drive deleting the data formatting does actually destroy the data so this is 100% wrong formatting does destroy the data deleting it when you're in an operating system does not

    Same with SSD, because the hardware gets damaged a bit every time you write something on it, so it just rewrites everything on the "deleted" data instead of giving a reset, theoretically doubling the lifespan
