I no gree. If na so, then space no suppose dey now but if person delete any file, space go free up... In actual sense, deleted files are completely erased (binary o, code o, algorithm o) only on some OS, like android, we do have LOST folder(or like) which is like a folder for super compressed deleted files. That is all I have to say

rozay12345:
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.

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)

No wonder Nigeria is not developing. Op asked a valid and smart question. Just look at the STUPID responses above? Fools.

@OP I am also waiting for an answer too.

On any hard disk, there is a table stored that says "File xxxxxxxx is stored in the following location(s): "
This ensures that for any request to file xxxxxxxxx, the drive knows where to go look for it. When a file is deleted, the first character of the filename is removed and marked as "unknown". This was the key to let the drive know that any of the locations listed for any filename starting with an unknown character were free to be overwritten with new data.
As long as no new data had been written over the sectors that originally housed that information, everything was still there and you could recover it simply by telling the table to restore the first character of the filename (I remember having to go through entire directories of data back in the 80s, trying to recall the first character of all the filenames so they could be undeleted, kind of like this:

"deleted file ?utoexec.bat -- First character: _"

Complete. Nightmare. Anyway, I digress)

So that allows a pretty easy method of recovering a file providing the sectors that housed it hadn't yet been overwritten. The Windows recycle bin simply delays this process by moving "deleted" files into a special holding area, noting the original location and date it was deleted. After a certain period of time, the "proper" delete takes place.

Now, some people realised that if they wanted to actually get rid of a file, a simple delete might not be sufficient, after all simply by restoring the data in the file table, there's a reasonable chance it might be able to be recovered, especially if it hadn't been a long time since the delete took place. So a method called "zero filling" was invented. This involved filling every byte of the original file with a "0", and then deleting the file. That way, even if you do restore the data in the file table, all you're going to get back is an empty file. It effectively ensures that the disk sectors are already overwritten at the time of deletion.
