When you delete stuff from your phone (pictures, videos etc.) where does all that data go?
In: Technology
Actually nowhere. Imagine storage as a bunch of words in a notebook. When you “delete” something you actually are just telling your computer (phone) that you don’t care about the contents of the notebook anymore. You throw that notebook in a pile that you designate as “good to write in”. The notebook isn’t actually cleared, you just no longer care that it has anything written in it.
Now when you have something else to write, you take out that notebook and simply write directly over the last thing that was there. The last thing isn’t “deleted” per se but is overwritten.
Actually with many programs you can look at your own storage and see if there is enough of your previous files to restore them from storage. If you never want this to happen (or you’re doing some shady stuff) there are programs that essentially are data “shredders”. They continuously overwrite a certain memory location until the data is completely unrestorable. From the analogy earlier it’s like if you took a permanent marker and just kept drawing over all the pages until you couldn’t make out what was underneath anymore.
