Can it truly be possible to restore a deleted file? And if it is, then just how can it be so? Doesn't deleting something mean you are erasing something into non-existence, much like erasing chalk writing off of a chalk board? Well, not really...
if it's anything close to erasing at all, it would be a lot closer to erasing something penciled onto a notepad.
Can you take a stab at guessing what I mean? I'll explain it to you in more detail...
In order to understand how to restore a deleted file, try to see it as somewhat similar to this; have you ever jotted something down in a notebook and then erased it away? After you've done that, have you then scribbled over that same area with the side of the pencil's point and could then see what you previously had written, just by the indentations made by the pencil you used, all showing up brightly through the penciled swipes? Obviously, performing file recovery tasks isn't done in exactly this same manner, but if you get the gist of this illustration, then you can understand the main point here - files always remain in one form or another, right on your hard disc, even after "deleting" them.
This is why some criminals who are involved in illegal computer activities get caught in the act - the evidence is always present and it gives them away, even if they purge their hard drives of all of their data (or so they believe).
Once the law enforcement authorities set their minds to finding evidence of criminal activity on a computer, they'll find it if it has ever existed on the hard drive even for a second.
To restore a deleted file only requires a certain software program to hunt it down and retrieve it.
Data retrieval programs that can restore a deleted file are simple and easy to use, and can really save the day of anyone who hopes to recover any data that was lost.
